Abstract:
A hand-held device with a sensor for providing a signal indicative of a position of the hand-held device relative to an object surface enables power to the sensor at a first time interval when the hand-held device is indicated to be in a position that is stationary and adjacent relative to the object surface, enables power to the sensor at a second time interval shorter than the first time interval when the hand-held device is indicated to be in a position that is moving and adjacent relative to the object surface, and enables power to the sensor at a third time interval when the hand-held device is determined to be in a position that is removed relative to the object surface.
Abstract:
A method and a device for determining what commands can be used to operate a receiving device (110) when a user operates a control device (105). After such a determination is made, a first command is transmitted to the receiving device from the control device (105) over a first communication interface and a second command is transmitted to the receiving device (110) over 5 a second communication interface. The communication interface that is selected depends on whether the control device can control the operation of the receiving device (110) with such a command directly or whether an intervening device (130/140) is required to translate the command from a first format to a second format.
Abstract:
A remote data concentrator receives signals from a plurality of sensors. The plurality of sensors are for use on an aircraft. Each of the sensors have their signals split between at least two flow paths, such that each of the sensors are provided with redundancy. The remote data concentrator is also utilized as part of an aircraft electrical control system.

Disclosed are methods, devices, systems and computer program products for communicating between at least one unit of a therapeutic fluid dispensing device and at least another unit of the dispensing device. The method includes performing a determination whether a first frequency can be used to transmit a message related to operations of the dispensing device, and transmitting the message based on the determination.
Abstract:
A multivariate environmental sensing system with redundant transmission pathways with a network of nodes detecting environmental conditions and processing a transmissible signal. Nodes use predetermined criteria to make periodic detections, maintaining a low power state between detections. Power is conserved by deciding whether detections are transmitted immediately, or may be stored for periodic transmission. The nodes power up and immediately transmit urgent detections, storing routine detections for delayed batch transmission. Nodes may transmit signals received from other nodes, passing along signals received from more distant nodes. Transmission may have a predetermined pattern, but the system alters this pattern if there is disruption to the system or pattern. Gateways process data from nodes and pass data to other gateways, on an immediate or deferred basis, to a control center, where data is analyzed. Control centers transmit programming instruction to the gateways and nodes in a retrograde fashion along the transmission pathways.
Abstract:
A system for wireless transmission of signals is provided. The system includes a mobile operator unit that is operable to transmit signals; and a base unit of a safety-critical device that is operable to receive signals from the mobile operator unit. The mobile operator unit is operable to categorize the signals to be transmitted as safety-relevant control signals and non-critical communication signals. Only the safety-relevant control signals are checked for error-free transmission. The non-critical communication signals are transmitted without error safety checking.
Abstract:
A detachable remote controller for an electronic entertainment device and a method for using the same are provided. The detachable remote controller includes a first infrared transmitter and a second infrared transmitter. The first infrared transmitter transmits signals to the electronic device while the detachable remote controller is coupled with the entertainment device. The remote controller is shaped in such a way to be docked within a cavity and flush with one surface of the entertainment device. The first infrared transmitter is aligned in the cavity such that the first infrared transmitter transmits signals to a light pipe embedded within the entertainment device. The second infrared transmitter is located at one end of the detachable remote controller to transmit signals to the entertainment device while the detachable remote controller is not coupled with the entertainment device.
Abstract:
A transmitter for transmitting an RF control signal to a remote system includes a user input device, a memory and a transmitter circuit. The memory includes control data associated with the remote device. The control data includes a first frequency and a second frequency. The transmitter circuit is coupled to the user input device and memory. In response to a single user input, the transmitter circuit generates a rolling code signal, transmits the rolling code signal at the first frequency for a predetermined amount of time, and, upon expiration of the predetermined about of time, transmits the rolling code signal at the second frequency.
Abstract:
A system for communication with addressable electronically-controllable appliances using a generalized pointing device is provided. The system includes a pointing device that can communicate with dissimilar types of target appliances from a position remote from those appliances and an appliance interface that makes the target appliances compatible with the pointing device. Use of the system is believed to allow the convenience associated with use of a computer's graphical user interface (GUI) to be realized in communication with physical objects, i.e. the target appliances. In an embodiment for one-way communication from a pointing device to a target appliance, the pointing device may comprise an actuator, an input-output interface, and a transmitter. In an embodiment configured for two-way communication between the pointing device and an appliance, the pointing device may further include a receiver. The appliance interface may include a receiver, an input/output interface, and a driver to convert received pointer command signals to corresponding functions of the appliance. In an embodiment configured for two-way communication, the appliance interface may further include a transmitter. The system may be configured for transmission using optical signals, radio-frequency signals, or both.
Abstract:
A method for communication with addressable, electronically-controllable appliances using a generalized pointing device is presented. The pointing device can communicate with dissimilar types of target appliance, and each appliance is associated with an appliance interface that makes the target appliance compatible with the pointing device. Use of the method is believed to allow the convenience associated with the use of a computer's graphical user interface to be realized in communication with physical objects, i.e. the target appliances. The method includes orienting the pointing device for reception of its pointer command signals by an appliance interface of the targeted appliance, transmitting a selection signal from the pointing device to the appliance interface, and transmitting a pointer command signal to the appliance interface. In an embodiment involving two-way communication between the pointing device and appliance interface, the method further includes observing appliance response information transmitted from the appliance interface to the pointing device. The method may include establishment of a line-of-sight transmission path between the pointing device and appliance interface for optical signal transmission. Additionally or alternatively, the method may include use of a non-line-of-sight transmission path for radio frequency signal transmission.
