Title: Point Of Purchase Display

Technical Field and Background:
Point of purchase displays are advertisements that can be positioned near or on a product that is being sold in a retail environment, so that potential purchasers may view the display with the product at the time of making a purchase decision. Many known point of purchase displays are formed from rigid plastic or cardboard, paper, or other materials, which can be easily damaged and/or are limited in their size, shape, attachment and positioning on the product, and present challenges in packaging and shipping the displays with the products. It is often desirable to attach a point of purchase display to the product during the manufacture and/or packaging of the product for shipment to a retailer. But the size and shape of such displays typically are limited to the size and shape of the product's box or other packaging. For example, folding a typical rigid point of purchase display panel to fit within a product package that is smaller than the display size may damage the display and/or cause the display to be less visually appealing when set up at the retail site. Packaging a paper display with the product may cause the display to be wrinkled, creased, torn or otherwise disfigured during transport. Furthermore, because packaging size is typically minimized for efficiency in delivery and storage of products, it has now been found desirable to provide point of purchase displays for a product that are larger than the product's packaging would otherwise allow. It has also been found that assembly and attachment of point of purchase displays to a product at a retail site can be expensive and require additional labor and logistics, either on the part of the retailer if they will do so, or on the part of manufacturers' representatives who are required to travel to the retail sites. Accordingly, it can be seen that needs exist for an improved point of purchase display. It is to the provision of an improved point of purchase display meeting these and other needs that the present invention is primarily directed.

Title: Method For Measuring Discovery Signal, Base Station, And Terminal

Technical Field and Background:
The small cell technology uses low-power wireless access nodes to extend the coverage range of a macro cell, distributes growing data flow of the macro cell, and increases the utility efficiency of radio spectrum resources. The LTE-Advanced system uses this technology to increase network capacity. Typically, the Small Cell has a small size, and its coverage range is between 10 meters to 2 kilometers. The Small Cell deployment scenario in the LTE network is composed of two levels: macro cell and small cell. The macro cell and the small cell can be deployed at the same frequency point, that is, co-channel deployment; or they can be deployed at different frequency points, that is, non-co-channel deployment; alternatively, the macro cell may not be deployed, and only the small cell is deployed. The small cell can be deployed in indoor environments and outdoor environments. It may be deployed sparsely or densely. The Small Cell is an interference-limited system, there are complex interference relationships between the macro cell and micro cell, as well as between the micro cell and the micro cell. Each cell dynamically schedules to serve terminals within the cell. In addition, as the UE moves, there are UEs continuously moving in and moving out of the small cell, the load and interference of the Small Cell system will show a significant fluctuation. Therefore, it must adopt a certain interference coordination method, such as small cell adaptive switching mechanism and adaptive power adjustment mechanism, to suppress and coordinate the interference in the Small Cell. The basic idea of the small cell adaptive switching mechanism is adaptively opening or closing some small cells with very low load to reduce inter-cell interference. An opened cell is called an activated cell, and a closed cell is called a dormant cell. The activated cell normally transmits data channels and common channels; the dormant cell closes data channels and some of common channels. However, both the activated cell and the dormant cell can transmit the cell discovery signal (DS) that is used for the cell discovery and selection, activation/deactivation judgment, and so on. The discovery signal is still under discussion, currently there are several viewpoints: 1) following the traditional PSS/SSS/CRS (Primary/Secondary Synchronization Signal, Cell-specific reference signals) signal; 2) using the modified PSS/SSS/CRS signal; and 3) using a new DS. The UE detects the DS of the activated cell and the dormant cell to discover and select a cell. For a dormant cell, if there is a UE detecting the discovery signal of a cell, it indicates that there are UEs existing under the coverage of the cell, and it may consider to activate the cell in order to serve these UEs. For an activated cell, if the UE detects the DS signal of a cell, if the DS signal of the cell is stronger than the DS signal of the current serving cell, it may consider switching to the cell; or although the DS signal of the cell is equivalent to or relatively weaker than the DS signal of the current serving cell, but for the load balancing consideration, if necessary, it may also consider switching to the cell. Therefore, the DS measurement is very important for operations such as discovery, selection, activation and deactivation of a small cell system. The DS measurement method can be a presence/absence detection, namely 0/1 detection, and it takes how many times it is detected within a certain time period as a measurement value; it can be a quantitative detection, that is, the RSRP (Reference Signal Receiving Power) detection/RSRQ (Reference Signal Receiving Quality) detection/SINR (Signal to Interference plus Noise Ratio) detection that takes the DS signal intensity or signal quality as the measurement quantity. There are different measurement needs for performing the DS presence/absence detection and the DS intensity detection, the number of samples required in the presence/absence detection is small, while the number of samples required in the intensity detection is large and the filtering time is longer, that is to say, the presence/absence detection and the intensity detection need to use different measurement patterns. In addition, for a scenario in which the Small Cells are deployed at different frequencies, the UE needs to carry out an inter-frequency detection on the DS of the inter-frequency cells.

Title: Hierarchical Spectrum Coordination

Technical Field and Background:
All wireless technologies use the airwaves to transmit and receive information. To allow many different technologies to communicate simultaneously, wireless spectrum is carved up into chunks of frequency bands, with radio frequency (RF) in particular lying in the range of 3 kHz to 300 GHz. RF bands in a given area may be either licensed or unlicensed, and an enterprise may have access to both. For licensed bands, entities generally pay a fee—or otherwise obtain rights—for the exclusive rights to transmit on assigned channels of specific bands in a geographic region. In unlicensed bands, virtually anyone following particular transmission protocols may transmit data across the bands without having to pay licensing fees. Licensing is generally very impractical for certain device uses, such as for smaller wireless devices that yet remains available in most regions. However, the fact that virtually any device may transmit in unlicensed space causes interference and problems in areas with numerous wireless devices or during times of high network traffic. As wireless technologies become more prolific, enterprises—or groups of enterprises—need to manage multiple, sometimes contentious, wireless infrastructures within a given geographic area. Wireless device traffic largely depends on the particular applications being performed on the devices in a given location. Streaming a video chat requires much more bandwidth than communicating e-mails. The frequencies an enterprise has licensed may quickly be consumed during peak hours, and services the enterprise has earmarked for the licensed frequencies may suffer interference or performance degradation if network capacity is not appropriately allocated to the wireless devices in the area. Some enterprises have proprietary radio management solutions that manage devices within a single spectrum range. For example, wireless vendors sometimes have software that automatically assigns access points in a wireless infrastructure to different channels. Such solutions are very focused in scope to their own solution and devices. If an administrator deploys non-cooperating devices (e.g., wireless security cameras and wireless projection receivers), the two sets of devices may operate independently and unknowingly compete for the same airspace. The resultant interference may degrade the performance of groups of devices.

Invention Disclosure:
Examples disclosed herein relate to efficient hierarchical radio frequency (RF) spectrum assigning across both licensed and unlicensed frequencies in a given area. Wireless devices in the area are detected by a spectrum manager, which also detects all available RF frequencies that are available. Conditional, relative, or absolute RF assignment rules received by an administrator or from an administrative device dictate the allocation conditions for assigning wireless devices to different frequencies, channels, channel widths, bands, durations, or other specifics of the available RF frequencies. Alternatively, RF spectra may be assigned reactively based on the current, historical, or future network usage on the available network frequencies.

Description of the Prior Art In current working environments, displays are heavily-used and almost replace paper to become the major media for displaying information. A display used in such a working environment is called a visual display terminal (VDT). According ANSI/HFS 100 (American National Standards Institute/Human Factors Society 100 ), a suggested illumination for a VDT environment is 300 to 500 lux. Please refer to FIG. 1 . FIG. 1 illustrates a situation while a prior art lamp 10 is used.

Title: Method For Controlling A Brake Pressure Booster

Technical Field and Background:
1. Field of the Invention The present invention relates to a method for controlling a brake pressure booster utilizing hydraulic brake pressure boosting. 2. Description of Related Art Hydraulically assisted brake pressure boosters are increasingly used instead of conventional vacuum-based brake pressure boosters. One reason for this is the additional cost of the vacuum supply in modern motor vehicles, because the intake manifold is not available as a vacuum source in diesel vehicles per se, and also an adequate intake manifold vacuum is no longer continuously available in vehicles with spark ignition because of occasional engine shutdown or operation with a wide open choke flap. In contrast, a supply pump for an electronic stability controller (ESC) can be used as a pressure fluid source in an advantageous manner with hydraulically assisted brake pressure boosters (in general, a pressure reservoir is still necessary in addition). There are synergy effects from such dual use of the ESC pump unit. Suitable brake pressure boosters are known e.g. from U.S. Pat. No. 4,678,243 A or DE 102011007095 A1, which are to be made the subject matter of this disclosure with respect to the detailed design of the brake pressure booster and the associated control arrangement. U.S. Pat. No. 8,038,228 B2 uses the brake pressure gradient as a triggering criterion for an additional pressure source. U.S. Patent Publication No. US20110270500 A1 activates the additional pressure source depending on the pressure in the tandem brake master cylinder. A common comparison test for brake systems of motor vehicles—which however is not part of legally specified tests—is the so-called AMS brake test, which refers to the German automobile magazine “Auto Motor and Sport.” The test consists essentially of maximally accelerating a vehicle laden with the permissible loading ten times in immediate succession from 0 to 100 km/h and then decelerating back by means of full braking with the antilock braking system responding. This test places special requirements on the temperature behavior of the brake system, especially with respect to brake fade. An AMS brake test of the hydraulic brake pressure assistance in current brake pressure boosters provides little or no benefit. A more detailed analysis shows this is apparently because the additional hydraulic pressure source is activated throughout; but the application points and activation criteria for activating the additional braking assistance with known brake controllers are so unfavorable that at the point in time of activation there is already such a high brake pressure that the common ESC pumps or the non-return valves disposed in the hydraulic path cannot transport any more brake fluid or supply the brake pressure booster.

Further upon exceeding a specified piston rod activation travel limit value, which lies at 20% to 100% of the available travel, preferably at 40% to 60% of the available travel. Furthermore, the speed of the vehicle, its lateral deceleration and its longitudinal deceleration can be used as criteria.
