Abstract: As taught herein, a floating current source outputs a load biasing current from a source terminal into an external load which may have a variable resistance, and sinks the load biasing current from the load into a sink terminal. Advantageously, the floating current source includes a single-transistor current sink having a bias control that sets the magnitude of the load biasing current desired, and further includes a single-transistor current source that self-biases from the float voltage developed on the external load to an operating point at which the single-transistor current source sources the desired magnitude of load biasing current. One or more AC shunts within the self-biasing network prevent any AC fluctuations present or impressed on the source terminal of the floating current source from changing the operating point of the single-transistor current source, thereby imparting a high effective impedance to the single-transistor current source.

Abstract: A video transport system is provided for transporting as 8B/10B coded video stream across a 64B/66B coded link, wherein forward error correction is provided without the overhead of the prior art. The system also provides a system with the ability to recover 64B/66B Encoded blocks that have corrupt Sync bits.

Abstract: According to one aspect of the teachings herein, a system includes first and second modules that respectively anchor host-side and device-side ends of an intermediate transport link that interconnects a USB host to a USB device. The system detects when the host activates an isochronous endpoint in the device for an isochronous IN data transaction, and the second module autonomously generates data requests for the device and forwards the isochronous data output from the device towards the first module. In turn, the first module buffers the data and provides it to the host in response to host's data requests. However, the first module blocks host requests from propagating to the device and it NACKs host requests until forwarded data is available from the second module. Such operation remains transparent to the host and device, while avoiding USB timing violations, even for extended intermediate transport links.

Abstract: When a lead used for taking a pet for a walk or leashing the pet to a place such as a kennel is pulled by the pet or a human during walk or while the pet is leashed, a portable electric power generator connected with the lead generates electricity using mechanical energy obtained by the pulling action. The electricity generated by the portable electric power generator is supplied for the electronic device attached to pet worn by the pet through a charging cable disposed along the lead inside or outside the lead, thereby charging a rechargeable battery inside the electronic device attached to pet. The electronic device attached to pet uses the electrical energy of the integrated battery to perform a predetermined operation (such as wirelessly reporting the current location of the pet, and wirelessly reporting information representing the sound of the pet). The electronic device attached to pet reports that the pet got away from a location where the owner exists and has gotten lost for a number of conditions.
