Abstract:
An electronic device for controlling a remote electronic device is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device enters a control state that is not a power off state and is not a power on state. The electronic device also generates a control message for a remote electronic device while in the control state. The electronic device further transmits the control message for controlling the remote electronic device while in the control state.
Abstract:
A remote control signal receiver includes a receiving sensor to receive a remote control signal for remotely controlling an electrical apparatus, a receiving signal processor to judge whether or not the receiving sensor received the remote control signal, to recognize a direction included in the remote control signal and to generate an internal signal in response to the direction in accordance with the receiving signal, and an intermittent controller to drive the receiving sensor intermittently during a standby period of the electrical apparatus.

Abstract:
A measuring device for measuring the relative rotational speed of a rotor which rotates with respect to a stator, having at least one inductive pulse generator which is supported by the stator and comprises at least one induction coil in which an electrical voltage which represents a rotational speed measurement signal for the rotational speed is induced by the rotation of the rotor provided with circumferential markings.
Abstract:
The present invention provides systems and methods for utilizing zero-power, energy-harvesting computational modules to provide secure and reprogrammable wireless communications with vulnerable devices comprising integrated circuits (ICs), including active implantable medical devices, electronic lock and key systems, credit cards, access cards, identification cards and passports. The zero-power, energy-harvesting computational modules are powered by radio signals received from an interrogator, and requests from the interrogator are authenticated using an encrypted challenge-response mechanism. Communications between the interrogator and the vulnerable device are enabled if the interrogator requests have been authenticated, thus preventing unauthorized requests from reaching the vulnerable device.
Abstract:
An electronic apparatus and a control method are provided that are capable of reducing power consumption. The electronic apparatus having a normal mode in which first electric power is consumed and a power-saving mode in which second electric power lower than the first electric power is consumed includes a first sensor and a second sensor whose power consumption is lower than that of the first sensor. In the power-saving mode, supply of power to the first sensor is restricted, the second sensor is set to the power-saving mode, a trigger for restoring the power-saving mode to the normal mode is detected by using the second sensor set to the power-saving mode, and the power-saving mode is restored to the normal mode based on the detected trigger.
Abstract:
A method for controlling a group of wirelessly controlled appliances comprising at least one appliance in a home automation network comprising a master controller, characterized in that it comprises: a reception step in which the master controller receives a wireless command intended for an appliance of the group, then a connection step in which the master controller connects the appliance to mains power, if the appliance was previously disconnected from the mains power, then a disconnection step in which the appliance is automatically disconnected from mains power.
Abstract:
A wireless sensor and actuator network includes a number of wireless nodes, each of which may be connected to any one or combination of analog sensors, digital sensors, and actuators, and is powered by an autonomous power supply such as a battery or solar panel. Since autonomous power sources may not have sufficient voltage for powering many types of analog sensors, digital sensors, and actuators, power management techniques are used in the node and in the autonomous power supply as needed to enable effective and long life operation of the node and connected devices. These power management techniques include the use of a low impedance energy reservoir and a variable voltage boost converter whose output voltage magnitude, duration, and operating times are software configurable and controllable. The power management techniques are particularly useful for operating a wide range of different types of sensors and actuators.
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:
An intermediate station transmits a supervisory signal sent form a given controlled device to a controlled device associate with the given device as a control signal. An intermediate-station input unit extracts a supervisory signal, which is a current signal superimposed on a signal transmitted through a data signal line, in every clock cycle. An intermediate-station output unit obtains the supervisory signal in every clock cycle, and outputs a control signal, which is a pulse-width-modulated voltage signal, onto the data signal line in the same clock cycle in which the supervisory signal has been extracted.
