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.
Abstract:
Described herein are systems, methods, devices, and other techniques for implementing smart windows, smart home systems that include smart windows, and user devices and applications for control thereof. A smart window, or photovoltaic window, may include a photovoltaic configured to generate electrical power from incident light onto the photovoltaic window, store the electrical power, and send the electrical power to an electronics package or various electrical loads including a wireless communication system, sensors, or window functions. The photovoltaic window may communicate with various smart home system devices such as hub devices and user devices, which may include the reception of control data at the photovoltaic window and the transmission of sensor data captured by the window sensors.
Abstract:
A presentation moderator assembly for facilitating nonverbal and nonphysical communication between a moderator and a presenter includes a base unit that is positioned in view of a presenter. The base unit has a first light emitter that is selectively illuminated to communicate to the presenter that the presenter may begin speaking. The base unit has a second light emitter that is selectively illuminated to communicate to the presenter that the presenter should begin finishing speaking. The base unit has a third light emitter that is selectively illuminated to communicate to the presenter to stop speaking. A remote unit is carried by a moderator and the remote unit is in electrical communication with the base unit. The remote unit selectively turns on each of the first, second and third light emitters.
Abstract:
Provided is an electronic device. The electronic device includes a communicator that wirelessly connects the electronic device to an external device, and a controller that controls the communicator and transmits a wake-up signal to the external device, in response to an input to turn on the power of the electric device, to instruct the external device in a standby state to initiate an audio output preparing operation. The standby state corresponds to a state in which the external device attempts to establish a connection.
