Abstract:
A wireless control device may include an antenna and a power harvester configured to generate power for the device from a radio frequency signal incident on the antenna. The device may further include an upconverter stage comprising a first port to receive a control signal to be upconverted and a second port to receive the incident radio frequency signal and to output the upconverted control signal at upper and lower sideband frequencies. The antenna may be coupled to the second port.
Abstract:
A remote control for an electronic device includes a plurality of keys, a power supply, a power control unit, a code modulating unit, and a transmitter. The plurality of keys generates different first electrical signals when actuated. The power supply is operable to power the remote control. The power control unit detects a voltage of the power supply, and generates a second electrical signal when the voltage of the power supply falls below a predetermined value. The code modulating unit generates different key code signals according to the different first electrical signals, and a switch code signal according to the second electrical signal. The transmitter converts the different key code signals and the switch code signal into different wireless signals, and transmits the different wireless signals to the electronic device.
Abstract:
The present invention is related to a multi-function remote control which is supplied power by a rechargeable battery. The multi-function remote control comprises a micro controller unit (MCU), a residual power display, a button unit, a current detector and a voltage detector. The MCU couples to the rechargeable battery and then charges or discharges the rechargeable battery. The current detector measures the current of the rechargeable battery and correspondingly outputs a current-value signal (Si) to the MCU. The voltage detector measures the voltage of the rechargeable battery and correspondingly outputs a voltage-value signal (Sv) to the MCU. Then, the MCU obtains the residual power of the rechargeable battery by means of analyzing the current-value signal (Si) and voltage-value signal (Sv), and then reveals the corresponding residual power by the residual power display. Whereby, the multi-function remote control might have functions of remote control, charging and revealing residual power.
Abstract:
A receiving module, checking module, and a controller are provided. The receiving module is configured for receiving external wireless signals. The checking module is configured for checking whether a current wireless signal comprises checking codes of a control signal which is configured for controlling the electronic device and, if yes, generating an activation signal. The controller is configured for switching the electronic device into a power-saving mode if no external wireless signal is received after a predetermined time period and switching the electronic device into a normal mode if the activation signal is received.
Abstract:
A remote control device includes: a vibration power generator configured to convert externally applied vibrations to electric power; a storage section charged with the electric power obtained by the vibration power generator; a switch provided between the vibration power generator and the storage section; and a control circuit configured to output a vibration instruction signal and turn the switch on when the remaining power of the storage section becomes smaller than a predetermined amount. The electronic apparatus instructs the user to vibrate the remote control device in response to the vibration instruction signal.
Abstract:
A monitoring device is for monitoring physical characteristics of a building material. The monitoring device is buried inside a block of the building material, and has a sensor to sense physical characteristics thereof. The sensor transmits a signal representative of the physical characteristics.
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.
Abstract:
Presented is a control system for augmenting a portable touch screen device (5) having integral processing capability. The control system includes an enclosure (1) configured for encasing the portable touch screen device, an internal docking connector (12) configured for communicatively mating with the portable touch screen device, and hard buttons (31, 32, and 33). 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.
