Abstract: A system and method for detection of multipath and transmit level adaptation thereto in ultrasonic locationing of a mobile device within an environment includes providing fixed ultrasonic emitters for transmitting ultrasonic bursts at predetermined times. A communication device measuring at least a direct signal of each ultrasonic burst and detecting multipath of each ultrasonic burst by comparing an amplitude of the direct signal with other signals related to the ultrasonic burst. If multipath is detected a controller increasing a transmit power level of the ultrasonic burst to insure the direct signal reliably remains above the detection threshold. If multipath is not detected reduce a transmit power level to the point detection is just possible. Results from non-multipath conditions are more heavily weighted when determining position as they are typically more accurate.

Abstract: A technique for the detection of an unauthorized wireless communication device includes monitoring of Bluetooth® communications activity by a Bluetooth® capable communication device. Any monitored communication activity is analyzed against parameters that are predefined to detect suspected illegal activity. If illegal activity is suspected by the analysis, an alert is generated for a system administrator. The predefined parameters associate illegal activity with; data that includes credit card numbers and expiration dates, credit card transaction logging information, non-discoverable devices, activity after store hours, exceedingly long activity, etc.

Abstract: A method and system for adaptive operation of a power amplifier of an RFID reader device enables more efficient power management of the reader device. The method includes transmitting an RF interrogation signal from an antenna of the RFID reader device (step 505). A reflected signal is then received as a partial reflection of the interrogation signal (step 510). A return loss value is then estimated by comparing at least one parameter of the interrogation signal and at least one parameter of the reflected signal (step 515). Finally, an operating point of the power amplifier is adjusted in response to the return loss value (step 520).

Abstract: A method, a system, and a server provide context aware multiple-input-multiple-output MIMO antenna systems and methods. Specifically, the systems and methods provide, in a multiple MIMO antenna or node system, techniques of antenna/beam selection, calibration, and periodic refresh, based on environmental and mission context. The systems and methods can define a context vector as built by cooperative use of the nodes on the backhaul to direct antennas for the best user experience as well as mechanisms using the context vector in a 3D employment to point the antennas in a cooperative basis therebetween. The systems and methods utilize sensors in the nodes to provide tailored context sensing versus motion sensing, in conjunction with BER (Bit Error Rate) measurements on test signals to position an antenna beam from a selection of several “independent” antenna subsystems operating within a single node, as well as, that of its optically connected neighbor.

Abstract: A Radio Frequency Identification (RFID) reader is provided that receives a digital input signal, converts the digital input signal to an analog input signal, and determines whether the digital input signal is an unmodulated signal or is modulated with information. When the digital input signal is modulated with information, the RFID reader filters the analog input signal to produce a filtered analog input signal and transmits the filtered signal. When the digital input signal is an unmodulated signal, the RFID reader bypasses the filtering of the analog input signal to produce an unfiltered analog input signal and transmits the unfiltered analog input signal.

Abstract: An imaging reader is operatively connected to a host system and captures light returning from a two-dimensional symbol having encoded characters, and processes the captured light into binary data. A controller in the reader or the host system determines from the binary data if the encoded characters are encoded in accordance with a local character set that is indicative of a local language, and translates the local character set to a global character set that is indicative of multiple global languages after determining that the encoded characters are encoded in accordance with the local character set. The encoded characters are processed by the host system controller in accordance with the global character set.
