Abstract: A complete telemetry system and methods for downhole operations. The telemetry system includes an instrumented near-bit sub located below the Mud Motor and connected to the drill bit as well as a conventional MWD tool located above the mud motor. Parameters such as inclination of the borehole, the natural gamma ray of the formations, the electrical resistivity of the formations, and a range of mechanical drilling performance parameters are measured. Electromagnetic telemetry signals representing these measurements are transmitted uphole to a receiver associated with the conventional MWD tool located above the motor, and transmitted by this tool to the surface via mud pulse signals. The system is particularly useful for accurate control over the drilling of extended reach and horizontally drilled wells.

Abstract: Embodiments are directed to power conversion circuits including a bypass circuit for bypassing an inrush current limiting resistor. In one embodiment, a power conversion circuit is provided that includes a bridge rectifier, a current limiting resistor, a controllable current switching device, and a driver. The current limiting resistor has a first terminal coupled to an output terminal of the bridge rectifier and a second terminal coupled to an electrical ground. The controllable current switching device has conduction terminals coupled in parallel with respect to the current limiting resistor. The driver is coupled between the first terminal of the current limiting resistor and a control terminal of the current switching device, and the driver controls an operation of the current switching device based on a current through the current limiting resistor.

Abstract: Methods, systems and apparatuses configured to isolate and/or damp vibration of refrigerant lines caused by, for example, the compressor are disclosed. A vibration control device can be configured hold a refrigerant line at a position that is away from the compressor. The vibration control device can help isolate the vibration, reducing or preventing the vibration from passing the vibration control device along the refrigerant line. A vibration-damping device can be configured to engage the refrigerant line so as to absorb/damp the vibration of the refrigerant line.

Abstract: The present disclosure provides an electronic apparatus that comprises a number of Universal Serial Bus (USB) device control modules, a microprocessor, a priority arbitration module, a USB host control module and a USB hub module. The USB device control modules are configured to receive from and send to a host a USB electric signal. The microprocessor is configured to generate a number of virtual USB hub modules in a memory. Each of the virtual USB hub modules is configured to generate a USB device enumeration signal, in response to an electric connection status between a USB electronic device and the USB hub module, and to send the USB device enumeration signal via a corresponding one of the USB device control modules to the host. The priority arbitration module is configured to, in response to the availability of the USB electronic device, transmit the USB electric signal issued from the host to the USB electronic device via the USB host control module and the USB hub module.

Abstract: Approaches for calling firmware runtime services of a basic input/output system. A special globally unique identifier and a name are sent to PURE virtual variable stores by an operating system. The PURE virtual variable stores identify the special globally unique identifier and the name, for example, by checking in the PURE virtual variable stores to ascertain if the special identifier and the name correspond to a firmware runtime service of the basic input/output system. A corresponding firmware runtime service of the basic input/output system is called. The firmware runtime service of the basic input output system then executes.

Abstract: A cushion pad for shows includes a top plate, a bottom plate and a flexible mediate portion connected between the top plate and the bottom plate. The flexible mediate portion includes a plurality of straight plates perpendicularly connected to the top plate and the bottom plate, and a serrated plate is connected between the straight plates extending from the top plate and the bottom plate.

Abstract: A nail gun back cover includes a back cover shell body made of magnesium alloy. The inner side of the shell body includes a first cylinder and a second cylinder surrounding the first cylinder extensively formed therein. A groove is formed between the first cylinder and the second cylinder. In addition, a valve mechanism is formed in the shell body. The valve mechanism includes a fixed valve securely connected to the first cylinder and a movable valve contained in the groove. The movable valve can move relative to the fixed valve so as to control the air flow. Furthermore, some elastic bodies are used to touch the end surfaces of the groove and the movable valve. Moreover, a fixed ring is securely fastened to the back cover, so as to limit the range of movement of the movable valve. In this manner, the overall weight of the nail gun is reduced, making the nail gun much easier to operate.

The subsidiary belt has a width smaller than the width of the main belt body.

Abstract: An internally disposed cooling device is provided. The cooling device includes a cooling member and a docket member. The cooling member includes a first cooling unit, a second unit and a cryogenic element. The cryogenic element has a cold surface that contacts the first cooling unit, and a hot surface that contacts the second cooling unit. Since the cold surface of the cryogenic element has a temperature much lower than that of the room temperature, the first cooling unit can thus produce cold and dry air to cool down the electronic apparatus. Meanwhile, the second cooling unit is employed to dissipate heat generated from the cryogenic element.
