604304

Abstract:

A medication patch compliance control unit system and method is disclosed. The control unit can include an attachment sensor, a user interface and a controller that receives signals from the attachment sensor and sends signals to the user interface. The control unit can include an attachment sensor, a wireless transceiver and a controller that receives signals from the attachment sensor and sends signals through the transceiver. The attachment sensor can be a temperature sensor, and the controller can determine attachment based on whether the sensor is reading temperatures in the normal body temperature range. The user interface can include visual and/or audible indicators. The control unit can include an expiration timer, and provide an expiration signal when the patch is expired. The transceiver can transmit medication patch data to a healthcare provider. The controller can record when the medication patch is attached to and detached from the patient.

International Classification:

H04B 10/25

Abstract:

Systems and methods for optical transmission of one-or-more out-of-band signals associated with audio-video signal communication are described. In one aspect, an optical receiver receives a first out-of-band electrical signal and a second out-of-band electrical signal from a video sink. The first out-of-band electrical signal may correspond to an audio-video stream previously received or concurrently being received from a video source optical transmitter at the optical receiver. The second out-of-band electrical signal may also correspond to the audio-video stream. The optical receiver may combine the first out-of-band electrical signal and the second out-of-band electrical signal into a transmit electrical signal. In one aspect, the optical receiver converts the transmit electrical signal into an optical signal, and transmits the optical signal to an optical transmitter via an optical communication channel.

Abstract:

Systems and methods to transmit audio-video signals over an optical communication channel are described. One aspect includes receiving a plurality of audio-video electrical signals at an optical transmitter. The optical transmitter may also receive a plurality of out-of-band electrical signals. The optical transmitter may collectively modulate the audio-video electrical signals to generate a composite electrical signal. In one aspect, the optical transmitter bias current-modulates a bias current level of the composite electrical signal using the electrical out-of-band signals, and generates a modulated electrical signal based on the bias current-modulating. The optical transmitter may convert the modulated electrical signal into a modulated optical signal using a laser diode, and transmit the modulated optical signal to an optical receiver over an optical communication channel.

International Classification:

H04N 7/22
H04L 5/16
H04N 7/01

Abstract:

Systems and methods for signal communication over an optical link are described. One aspect includes receiving a source CONFIG signal from a DP master device and a sink CONFIG signal from a sink terminal. The source and sink CONFIG signals are analyzed. It is determined whether a signal transmission mode is a DP protocol. For a DP protocol, a pair of source AUX signals is received from the DP master device. A pair of sink AUX signals is received from the sink terminal. Communication resource contention between the source and sink AUX signals is identified. A communication direction of the communication resources is transitioned to give the source AUX signals precedence over the sink AUX signals. The source AUX signals are transferred to the sink terminal via the communication resources. The direction of the communication resources is again transitioned. The sink AUX signals are transferred to the DP master device.

Abstract:

Systems and methods for optical data interconnection are described. One aspect includes a first signal converter that converts first high-speed HDMI electrical signals into high-speed HDMI optical signals, and transmits the optical signals over a first optical communication channel. A second signal converter encodes first low-speed HDMI electrical signals, converts these encoded signals into low-speed HDMI optical signals, and transmits these optical signals over a second optical communication channel. A third signal converter receives the high-speed HDMI optical signals, and converts these optical signals to second high-speed HDMI electrical signals. A fourth signal converter receives the low-speed HDMI optical signals, converts these optical signals to second low-speed HDMI electrical signals, and decodes the second low-speed HDMI electrical signals.
