TL;DR: In this paper, the authors proposed a wideband ultra wideband (UWB) communication protocol with a low EIRP level (−41.3dBm/MHz) for unlicensed operation between 3.1 and 10.6 GHz.
Abstract: Before the emergence of ultra-wideband (UWB) radios, widely used wireless communications were based on sinusoidal carriers, and impulse technologies were employed only in specific applications (e.g. radar). In 2002, the Federal Communication Commission (FCC) allowed unlicensed operation between 3.1–10.6 GHz for UWB communication, using a wideband signal format with a low EIRP level (−41.3dBm/MHz). UWB communication systems then emerged as an alternative to narrowband systems and significant effort in this area has been invested at the regulatory, commercial, and research levels.

TL;DR: In this paper, the authors give an overview of spatial identification of modulated backscatter UHF RFID tags using RF phase information, and describe three main techniques based on PDOA (phase difference of arrival): TD (Time Domain), FD (Frequency Domain), and SD (Spatial Domain).
Abstract: In this paper, we give an overview of spatial identification (determining position and velocity) of modulated backscatter UHF RFID tags using RF phase information. We describe three main techniques based on PDOA (Phase Difference of Arrival): TD (Time Domain), FD (Frequency Domain), and SD (Spatial Domain). The techniques are illustrated with modeling and simulation example in free space and in presence of multipath using a multi-ray channel model for amplitude and phase of the received tag signal in deterministic environment. We also present and discuss the experiments performed in a real RFID warehouse portal environment.

TL;DR: In this paper, a touch screen has several piezoelectric regions within a material layer that may generate a voltage when deformed in a localized area, and the detected voltage signals are then used to extrapolate the position of the localized area in which the pieziolectric layer was deformed (e.g., from a finger touch or a stylus).
Abstract: A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having several piezoelectric regions within a piezoelectric material layer that may generate a voltage when deformed in a localized area. The piezoelectric layer may be disposed between sensor layers of rows and columns of sensor traces for detecting the voltage generated at any particular piezoelectric region. The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen and detect multiple touch locations.

Abstract: A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having a piezoelectric material layer that may generate a voltage when deformed in a localized area. The piezoelectric layer may also include a pattern of sensors for detecting the voltage generated. The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen.

TL;DR: In this paper, a system consisting of two or more item storage bins, each item storage bin comprising: a wireless communication tag emitting a wireless signal having data identifying the item storage container on which the tag is positioned, and an indicator activated by receiving a feedback signal identifying the storage container.
Abstract: A system comprises two or more item storage bins, each item storage bin comprising: a wireless communication tag emitting a wireless signal having data identifying the item storage bin on which the wireless communication tag is positioned, and an indicator activated by receiving a feedback signal identifying the item storage bin on which the indicator is positioned; and a personal device comprising: a wireless communicator configured to communicate with the wireless communication tags, and a controller coupled to the wireless communicator and configured to identify one of the item storage bins from the wireless signal, and in response to identifying the one item storage bin, sending the feedback signal through the wireless communicator to the indicator.
