Abstract:
A method and a device for power-saving operation of a plurality of RFID data carriers, whereby the RFID data carrier has a transmission and reception antenna, by way of which data are sent to and received from a read/write unit, by means of a radio signal, and the data carrier is configured for reception of an energy-saving signal that puts the data carrier into a so-called sleep mode. The read/write unit sends a so-called conditional sleep command to all the RFID data carriers, and the RFID data carriers receiving these data in the transmission field compare the transmitted condition with a status/data detected in the RFID data carrier, whereby the condition detected in the RFID data carrier depends on a sensor input that is connected with the RFID data carrier. The transmission of the signals between the read/write unit and the data carrier is formed by means of a transmission/reception antenna disposed on the read/write device, and a correspondingly disposed transmission and reception antenna disposed on the data carrier.

At least one of the hard buttons is functionally configured for use with an application program running on the portable touch screen device. The control system includes further includes a processor (50, 51, 52, 53) configured for converting button actuations into a digital format, and a first facility for communicating the digital format to the portable touch screen device via the internal docking connector. The application program is configured such that, during operation, the application program communicates the status of the one hard button to at least one external device.
Abstract:
A distinct dealing shoe having no shuffling functionality receives a shuffled, randomized or ordered group of cards. The cards may be mechanically moved one at a time from a receiving area for the deck to a buffer area where more than one card is temporarily stored. The cards in the buffer area are then mechanically moved to a card delivery area where the cards may be manually removed, one at a time, by a dealer. The cards are read one at a time inside of the dealing shoe, either before the buffer area or after leaving the buffer area, but preferably before the cards are being manually removed from a card delivery area. Information from the card reading may be used for game tracking, hand tracking, player information, and other security issues at casino table card games.
Abstract:
A device for eliminating standby power consumption of an electronic appliance with a system capable of automatic power-off is provided, which includes: a power-on signal wireless transmitting unit; a control unit; a wireless signal receiving unit, connected to the control unit; a controlled electronic appliance power supply switch unit, connected to the control unit, the power supply unit, the external power source and a power input end of a controlled electronic appliance; a power supply unit of the device, connected to the control unit, the controlled electronic appliance power supply switch unit and the external power source. In the device for eliminating standby power consumption of an electronic appliance with a system capable of automatic power-off, a flexible button capable of being adhered to a surface of a switch button of a different electronic appliance is used, so the electronic appliance can be powered on by pressing the button only once like a normal operation. Meanwhile, a standby current value of the controlled electronic appliance can be detected and memorized, thereby avoiding that the standby electronic appliance or normally working electronic appliance might be unable to be turned off due to different standby power consumption of different electronic appliances.
Abstract:
Systems and methods of extending battery life in inventory control devices are disclosed. A passive receiver configured to wirelessly receive an initiation signal having an associated energy field from a remote control system and to output a mode change signal is provided. The passive receiver is configured to be powered by an energy field associated with the initiation signal. A functional module coupled to the passive receiver and configured to be powered by a self-contained power source when the functional module is in an active mode is provided. The functional module is further configured to receive the mode change signal from the passive receiver and to change from an inactive mode to the active mode. The functional module draws more power from the power source in the active mode than in the inactive mode.

Abstract:
The invention describes a method of actuating a switch (S) between a device (Di) to be controlled and a power supply (P), which method comprises the steps of generating a first electrical signal (14) in a remote control unit (10) and converting the first electrical signal (14) into electromagnetic radiation (EM) by means of a first transmitting antenna (Ti) of the remote control unit (10). A first detecting antenna (Ri) of a remote control interface module (20) of the device (Di) to be controlled detects the electromagnetic radiation (EM) to obtain a second electrical signal (24), which is passively converted into a switch actuating signal (25). The switch actuating signal (25) is actuated to switch the device (Di) to be controlled between an operating mode in which current is drawn from the power supply (P) by the device (Di) during operation, and an inactive mode in which the device (Di) is completely disconnected from the power supply (P) so that no current is drawn by the device (Di). The invention further describes a system (1) for actuating a switch (S) between a device (Di) to be controlled and a power supply (P). The invention also describes a remote control interface module (20) and a remote control unit (10).
