Abstract: A method of preventing disjunctions in a power distribution unit having a plurality of output connectors is disclosed. A power level of each of the output connectors is sensed. It is detected that the power level of a given output connector exceeds a fixed power limit. In response to the detection, a delivery of power by the given output connector is stopped while maintaining a delivery of power by a remainder of the output connectors. Power delivery may be resumed in response to receiving a user command to rearm the given output connector. A power distribution unit adapted to prevent disjunctions is also disclosed.

Abstract: A communication system and method are provided for remotely reproducing a touch pattern or gesture as a vibrotactile output. At a touch screen, a first user device receives a touch pattern by a first user, characterizes the touch pattern as a touch pattern data based upon time and intensity of touch at a plurality of array points of the touch screen, and communicates the touch pattern data to a network. A tactile array patch of micro-vibratory devices is attachable to a garment and worn by a second user. The touch pattern data is wirelessly received from the first user device via the network. Vibration of selected micro-vibratory devices of the tactile array is modulated in timing and intensity in response to the touch pattern data to reproduce the touch pattern.

Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

Abstract: Embodiments are directed to restricting access to Radio Frequency Identification (RFID) tag information based on location. Access to RFID tag information may be restricted at the reader level, at the requester level, and at the network level. When reader-level restrictions exist, devices may be prevented from inventorying tags and retrieving information from tags. When requester-level restrictions exist, a requester or device may be prevented from receiving tag information from inventoried tags or a network. When network-level restrictions exist, a network may discard or otherwise restrict tag information received from devices.

Abstract: In a biometrics system for a building entrance unlocking or a bank account authentication, reference information registered under administration by the system is transmitted to a room or mobile-phone for private storage, with the original reference information deleted from the system. Biologic information gotten upon authentication is transmitted through wireless system to the room or mobile-phone for comparison with the reference, the result being returned to the system. Or, the reference is tentatively sent back to the system for comparison with the gotten biologic information. The biologic information sent to mobile-phone also includes health control information for storage and display. Mobile-phone also can receive blood pressure information at a waiting lounge of medical institution though wireless local communication even if the main power shut down. The communication between the biometrics system and the mobile-phone is encrypted.

Abstract: Medical procedure related objects (e.g., instruments, supplies) tagged with transponders are accounted for in a medical procedure environment via a medical object accounting system using a number of antennas, and optional readers. A first set of antennas is configured to interrogate sterile fields and/or non-sterile fields which do not encompass a body of a patient to account for the objects proximate a start and an end of a medical procedure. Readers (e.g., symbol, RFID) may be employed. A database is maintained with information including a current status of each instrument or supply, for instance as checked in or checked out. On notification of a discrepancy, a handheld antenna and/or second set of antennas interrogate a volume encompassing a body of a patient for retained instruments or supplies. The system is automatically configured (e.g., loading appropriate software) on communicative coupling of a device (e.g., antenna, reader, peripheral device).

Abstract: A method for authorizing the use of a motor vehicle, in particular a two-wheeled or four-wheeled motor vehicle, which has a first and a second antenna where the first antenna and the second antenna are spaced apart from each other, by a portable identification device which has an identification transmitter antenna. In order to increase the manipulation security of a known method, it is determined whether the identification device is moving toward the motor vehicle. This can on the one hand be determined in that the identification device repeatedly identifies the field strength of the signals emitted by the motor vehicle and identifies whether the field strength or field strengths is or are increasing. This can on the other hand be determined in that the identification device repeatedly determines the angle between the signals emitted by the motor vehicle and examines whether the repeatedly determined angles are increasing.

Abstract: A method for operating an access control comprises creating a plurality of wake-up schedules for a wireless transceiver. Each of the plurality of wake-up schedules may be configured to control how frequently the wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the wireless transceiver may be different from another one or the plurality of wake-up schedules for the wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the wireless transceiver such that a duration of time between wake-ups for the wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for the wireless transceiver may be configurable by an administrative user via an interface.
