  • Automatic frequency hopping method for use with wireless device
    Patent number: 8204096
    Abstract: An automatic frequency hopping method is provided for use with a wireless device. The wireless device could transmit data in two or more communication frequency bands. According to the counts of successful data transmission in respective communication frequency bands, the reasons of communication failure are analyzed. According to the reasons of communication failure, the automatic frequency hopping method discriminates whether a frequency hopping procedure is performed. Since the frequency hopping procedure is performed when a proper frequency hopping condition is satisfied, the automatic frequency hopping method could achieve the power-saving purpose and avoid the wireless communication interference with other wireless devices.

    Patent number: 8198877
    Abstract: A low voltage drop out (LDO) regulator is disclosed. The LDO regulator has a voltage buffer for receiving an input voltage containing a DC component and an AC component, converting the input voltage into a converted voltage having a lower DC component and an AC component following that of the input voltage; a control stage applied with the converted voltage; and an output stage applied with the input voltage. The output stage is controlled by the control stage to output an output voltage of a specific level. In the LDO regulator, elements of small sizes can be used to save a layout area thereof. In the meanwhile, the LDO regulator can maintain a high power supply rejection ratio (PSRR) characteristic.

  • Isolated stacked die semiconductor packages
    Patent number: 8198132
    Abstract: Semiconductor packages that contain isolated, stacked dies and methods for making such devices are described. The semiconductor package contains both a first die with a first integrated circuit and a second die with a second integrated circuit that is stacked onto the first die while also being isolated from the first die. The first and second dies are connected using an array of metal connectors containing both a base segment and a beam segment extending over the first die and supporting the second die. This configuration can provide a thinner semiconductor package since wire-bonding is not used. As well, since the integrated circuit devices in the first and second dies are isolated from each other, local heating and/or hot spots are diminished or prevented in the semiconductor package. Other embodiments are also described.

  • Low-voltage connection with safety circuit and method for determining proper connection polarity
    Patent number: 8199024
    Abstract: A safety circuit used in low-voltage connecting systems leaves the two low-voltage systems disconnected until it determines that it is safe to make a connection. When the safety circuit determines that no unsafe conditions exist and that it is safe to connect the two low-voltage systems, the safety circuit may connect the two systems by way of a “soft start” that provides a connection between the two systems over a period of time that reduces or prevents inductive voltage spikes on one or more of the low-voltage systems. When one of the low-voltage systems has a completely-discharged battery incorporated into it, a method is used for detection of proper polarity of the connections between the low-voltage systems. The polarity of the discharged battery is determined by passing one or more test currents through it and determining whether a corresponding voltage rise is observed.

  • Image frame transmission method for data overrun control
    Patent number: 8194137
    Abstract: An image frame transmission method for use in a network transmission system is provided. The network transmission system includes an image sensor and an image processor. Firstly, a first image data segment of an image frame captured by the image sensor is outputted to the image processor in response to a first state of a control signal after an initial signal has been asserted by the image processor. Then, the output of a second image data segment of the image frame following the first image data segment to the image processor is delayed in response to the transition of the control signal from the first state to a second state. Afterward, the second image data segment is outputted to the image processor in response to the transition of the control signal from the second state to the first second state.
