Abstract:
A peripheral apparatus includes an application program. The peripheral apparatus couples to the host system and automatically install the application program into the host system. Thus, the peripheral apparatus of the present invention does not need extra floppy disks or CD-ROM containing the application program. This aspect of the present invention is to avoid intervention for user, e.g., losing the floppy disks or CD-ROM.
Abstract:
A heat sink base (10) includes a rectangular body (11) made of aluminum and a circular core (12) made of copper. The body defines a circular through opening (111). A diameter of the opening is slightly less than a diameter of the core. The core is attached within the body according to the following steps: a) pressing the core into the through opening of the body; b) stamping the core to cause it to plastically deform in radial directions and thereby become firmly combined with the body; and c) removing any burring of the core flowing out from the opening such that surfaces of the core and the body are coplanarly smooth.
Abstract:
A pincers includes two main bodies, a fixing member, a treatment member, a tightening member and a resilient member. By utilizing the treatment member, the fixing member and the resilient member disposed between the main bodies and the fixing member, the pincers has a good mating relationship and can be easily assembled so that the using effect of the pincers is improved.
Abstract:
A method to distribute water from a private water tank to a user site includes connecting the private water tank to three parallel low pressure Variable Frequency Drive (VFD) pumps, two parallel high pressure VFD pumps, a pressure reducing valve (PRV), a tank level control valve, a flow meter, two pressure gauges, and two pressure transducers; controlling the three parallel low and two high pressure VFD pumps using a PLC programmed with at least first, second, and third low pressure pump set operation curves (LPPSOCs) each specifying a low pressure pump operation set point (B) and a PRV operation set point (F) at each of first, second, and third flow rates and first and second high pressure pump set operation curves (HPPSOCs) each specifying a high pressure pump operation set point (G) and a high pressure pump energizing set point (E) at each of fourth and fifth flow rates.
Abstract:
A pliers includes a first body including an engaging groove, a second body, and a tap-button mechanism. The second body is pivoted with the first body, and the first body is pivotable relative to the second body. The tap-button mechanism includes two positioning grooves at the second body and a tap button pivoted on the second body. When the first body comes close to the second body, the tap button can be tapped to a first position and engaged in the engaging groove. Thus, the first body is blocked and cannot pivot relative to the second body. The tap button can be tapped to a second position and detached from the engaging groove. Thus, the first body is pivotable relative to the second body. A positioning block is extending from the tap button and can be engaged in any of the positioning grooves for positioning the tap button.
Abstract:
Uplink power control in a macro cell in a wireless network comprises transmitting a reference signal from a base station device to at least one wireless device within the macro cell. The macro cell comprises the base station device and at least one radio transmitter device that is communicatively coupled to and remote from the base station device. The base station device and one or more radio transmitter devices could be selected to be a transmission point, a reception point or a combination thereof, for each wireless device. Information relating to a transmission power of the base station device is also transmitted to the at least one wireless device. An uplink signal is received from the at least one wireless device containing information relating to an uplink power determination that is based on the reference signal and the information relating to the transmission power of the base station device.
Abstract:
A user equipment (UE) is arranged to send an uplink power reference signal to an enhanced Node B (eNB) associated with multiple reception points (RPs), to receive identification of an RP set and a downlink reference signal power level, to determine a path loss estimate for each downlink reference signal received from RPs of the RP set, to determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the RP set, and to use the determined uplink power level during communication with the multiple RPs.
Abstract:
A main digital-to-analog converter (DAC) receives at least one input and generates an adjusted input. A SAR unit generates a code for controlling the main DAC based on a comparison output of a comparing unit that receives the adjusted input. A reference generator, under control of the generated code, generates at least one reference voltage, which is then forwarded to the comparing unit in each corresponding cycle for defining a search range of each cycle, wherein an absolute value of the reference voltage of a latter cycle is less than the reference voltage of a former cycle such that the search range of the latter cycle is smaller than the search range of the former cycle, and search ranges of all the cycles are centered at a base voltage.
