Abstract:
A collapsible container includes a rectangular bottom, a front and a rear rectangular wall pivotally turnably connected to a front and a rear edge, respectively, of the bottom along two folding lines, two rectangular side walls pivotally turnably connected to two lateral ends of each of the front and the rear wall along two folding lines, and two locating flaps pivotally turnably connected to two lateral edges of the bottom along two folding lines. Each of the two locating flaps is an isosceles triangle having two equal lateral sides separately corresponding to a diagonal of the sidewall. Moreover, fastening elements are correspondingly provided on an inner surface of each side wall and an outer surface of the locating flap to enable detachable connection of the side walls to the locating flaps and accordingly free collapse and extension of the container.

Abstract:
In an HDMI system, the clock regenerator proposed by the HDMI specification may suffer external noise because the input clock of a phase lock loop circuit in a sink device of the HDMI system is too slow. This slow input clock causes the phase lock loop circuit unable to adjust and reduce the jitter of an audio clock regenerated in the sink device. Therefore, one embodiment of the present invention provides a clock regenerator to extract the relationship between the regenerated audio clock and a video clock received by the sink device from other source devices. The clock regenerator may comprise a phase lock loop circuit, a recovery circuit, a crystal oscillator and a tracking circuit. The crystal oscillator generates a crystal clock. The phase lock loop circuit receives the crystal clock and regenerates an audio clock. The recovery circuit extracts the relationship between the audio clock and the received video clock. The tracking circuit tunes the frequency of the crystal clock based on the extracted relationship.
Abstract:
A standby circuit and method for a display device is disclosed. A detector detects voltage drop of the first termination resistor of a positive path of a clock channel, and the second termination resistors of a negative path. Upon detecting the voltage drop, a switch controller disconnects the positive path or the negative path that has the detected voltage drop, thereby saving power in the standby mode of the display device.

Abstract:
A reference voltage generator is provided. The reference voltage generator includes a bandgap reference circuit, a level shifter and a voltage divider. The bandgap reference circuit includes a current generator and a first BJT. The current generator outputs a reference current. The first BJT flows in the reference current from its emitter via a first resistor and has its collector and base grounded, such that a bandgap reference voltage and a first bias voltage can be output at the connection between the current generator and the first resistor and at the emitter of the first BJT. The level shifter is coupled to the bandgap reference circuit and outputs a second bias voltage higher than the first bias voltage and unequal to the bandgap reference voltage. The voltage divider is connected between the second bias voltage and the bandgap reference voltage and outputs a reference voltage therebetween.
Abstract:
A data communication system comprises a transmitter and a receiver. A plurality of current mode drivers at the transmitter are used to transmit clock and data signals to the receiver. A plurality of current mode sinks at the receiver are used to receive the transmitted clock and data signal. The present invention provides an improved current mode interface receiver with a process insensitive common mode current extraction circuit. The proposed common mode current extraction circuit will generate a current reference based on the received clock signal, so as to accurately interpret the received clock and data signals.
