摘要:
A remote jack pack has a video input jack that receives a video signal, an audio input jack that receives an audio signal, a video output that transfers the video signal to a television, an audio output that transfers the audio signal to the television, and a control output that automatically supplies control signals to the television. The control signals indicate the availability of the video and audio signals for processing by the television. The television has a tuner that supplies video and audio signals of a selected channel, a video connector that receives video from the remote jack pack, an audio connector that receives audio from the remote jack pack, a control connector that receive control signals from the remote jack pack, and a processor that is responsive to the control signals to selectively control display of the video and audio signals from the tuner and the video and audio signals from the video and audio connectors.

摘要:
A mobile device is bonded to a controllable device by reading a code on the controllable device, banding the mobile device to the controllable device by use of the code, and transmitting a remote control signal from the mobile device to control a controllable function of the bonded controllable device so that only the bonded controllable device responds to the remote control signal by performing the controllable function.

An encrypted program received in an MPEG transport stream is decrypted by receiving a message in the MPEG transport stream, wherein the message contains a key, decrypting the encrypted program based on the key, and replacing the message in the MPEG transport stream with a null packet.

A microplate for polymerase chain reaction (PCR) comprises a substrate having a metallic material for heating PCR samples, and a barrier layer disposed adjacent to the substrate. In some cases, the barrier layer is formed of a first polymeric material. The microplate includes one or more wells for containing PCR samples. The one or more wells are formed of a second polymeric material sealed to the barrier layer. In some cases, the substrate can provide a PCR ramp rate of at least about 5° C./second.
摘要:
An RF signal source having a camera that provides a camera output, an encoder that encodes the camera output in a compressed digital format, and a modulator that digitally encodes and modulates the compressed camera output and that provides the digitally encoded, modulated, and compressed camera output as an RF output of the RF signal source. The camera, the encoder, and the modulator may be contained in an enclosure. Additionally or alternatively, the encoder, the modulator, and at least part of the camera may be formed on a semiconductor substrate.

An ink delivery system for a printer. In one embodiment, the system includes an ink supply that contains ink to be delivered to a printhead of the printer and an ink buffer having a capacity that is smaller than a capacity of the ink supply, the ink buffer being configured to be repeatedly filled with ink from the ink supply and to deliver that ink to the printhead.
摘要:
A device for providing a controlled maximum rate of descent down a rope and fall arrest. The device includes a movable cam that in response to tension on a rope pivots into a closed position, jamming the rope within the device and arresting a fall. Force applied to a torque arm coupled to the cam allows the cam to be pivoted to its open position, which allows rope travel. As cam is opened, the rope travels a more sharply angular path through the device, which creates a frictional force on the rope sufficient to limit the maximum rate of descent.
