Abstract:
The present invention discloses a strain relief collar for use with an accessory associated with a mobile device and its method of making. The first step is the making of an outer molded body having an engagement portion with a cutout. The second step is inserting a cord into the outer molded body. The third step is the forming of an inner molded body having a hooking portion extending outward from the periphery thereof and beyond the cutout for engaging with an accessory. The present invention also discloses another strain relief collar for use with another accessory associated with a mobile device and its method of making. The first step is connecting the cord to an electrical component associated with the accessory. The second step is the forming of an inner molded body. The third step is the forming of an outer molded body.
Abstract:
A signal compensation circuit of a bus is disclosed in the present invention, wherein the amplitude of a surge is obtained by inputting a test pattern into the bus and comparing a reference voltage and a peak-value signal filtered out from the bus. For continual correction of the damping resistance, the test pattern can be inputted into the bus repeatedly to optimize the effect of the compensation. Then, a proper damping resistor is selected and connected to the bus in series to absorb the energy of the surge. The signal compensation circuit is embedded in the chip, such as in the south bridge.
Abstract:
An apparatus for indicating clock skew within integrated circuits (ICs) of a system. There are first and second IC chips operating on respective clocks in the system. According to the invention, the first IC chip operating on a first clock is configured to provide the first clock as output. The second IC chip operating on a second clock has a detection circuit to receive as input the first and the second clocks and to generate a compare signal as output, where the width of the compare signal is proportional to the amount of skew between the input clocks. The second IC chip also includes a sampling circuit coupled to receive the compare signal. With the sampling circuit, an output signal indicative of skew existing between the first and the second clocks can be asserted according to the compare signal.
Abstract:
A microphone includes a casing having an open side and a lid mounted to and covering the open side of the casing. A circuit board and a mounting plate are mounted in the casing. An audio conversion unit and a switch are mounted on the circuit board and electrically connected with each other such that activation of the switch controls on/off of the audio conversion unit. The lid includes a pivotal portion pivotably engaged with an end of the mounting plate distant to the switch, allowing the other end of the lid to pivot relative to the mounting plate between an activating position for pressing against and activating the switch and a non-activating position disengaged from the switch. A returning member is mounted between the lid and the casing for returning the other end of the lid to the non-activating position.
Abstract:
An in-ear earphone includes a shell and a sound output device. The shell has a first engaging portion. The sound output device has a sound tunnel, a second engaging portion and a speaker. The speaker is disposed between the sound tunnel and the second engaging portion coaxially with the sound tunnel. The second engaging portion is movably engaged with the first engaging portion. The angle between the shell and the sound output device is adjustable so that the sound tunnel can be suitably plugged into individual user's ear canals.

Abstract:
A method and a related apparatus for using a dynamic random access memory (DRAM) in substitution of a hard disk drive in a computer system. The computer system has a request format transformation module for transforming a hard disk request signal into a corresponding memory request signal, a memory read/write control circuit for accessing the DRAM, and a memory refresh circuit for periodically refreshing the DRAM to maintain data stored in the DRAM. When the computer system issues the hard disk request signal, the hard disk request signal is transformed into the corresponding memory request signal to access the DRAM instead of a hard disk drive. In addition, when the computer system executes an S4 or S5 state according to the specification of advanced configuration and power interface, the memory refresh circuit will repeatedly refresh the DRAM.
Abstract:
A method and related apparatus for utilizing an ACPI to maintain data stored in a DRAM includes a processor, a DRAM, a south bridge chipset, and a rechargeable battery device. The south bridge chipset includes a system controller, a buffer, a memory controller, an integrated device electronics controller, and a data conversion circuit. The data conversion circuit converts a hard-disk access command transmitted from the system controller into a memory access command of the memory controller. The memory controller accesses the buffer and the DRAM by executing the memory access command. When the computer system enters a power-saving mode, a switch is turned on allowing the battery device to constantly self-refresh the DRAM for maintaining the data stored in the DRAM. When the computer system powers up, the switch is turned off and the battery device is recharged.
Abstract:
An embedded control unit is installed in a notebook computer, so as to take the place of the programmable processor in many conventional notebook computers for controlling peripheral devices. The embedded control unit includes a plurality of peripheral controllers, so as to control the peripheral devices usually used by typical notebook computers. The peripheral controllers can be directly connected to the peripheral devices, according to the specifications for different types and/or brands of notebook computers. In addition, the peripheral controllers can achieve control of the peripheral devices according to the non-adjustable internal register settings. In this way, the control of the peripheral devices can be achieved without using firmware, thereby simplifying the notebook computer development process and reducing the development cost.
