Abstract: A golf club head and a method of making the golf club head including bonding tape. The method additionally includes positioning the first piece, the second piece, and the bonding tape, interposed between the first piece and the second piece, in a vacuum bag, and reducing a pressure within the vacuum bag, relative to a pressure external to the vacuum bag, such that the vacuum bag collapses onto the first piece and the second piece and compresses the bonding tape between the first piece and the second piece. The method also includes heating the bonding tape, at least to a curing temperature of the bonding tape, when the pressure within the vacuum bag is reduced.

One example level-shifting circuit generally includes a node for receiving an input signal ranging between a first voltage level and a second voltage level, a first circuit path coupled to the node and configured to level shift the input signal to generate an output signal ranging between a third voltage level and a fourth voltage level, a pulse generator coupled to the node and configured to generate a pulse based on a transition in the input signal between the first and second voltage levels, and a second circuit path connected in parallel with the first path and configured to temporarily short the first path based on the generated pulse.

Abstract: A session manager is used to manage selection of a remote host for a session in response to a request that is associated with a user. The session manager uses resource information obtained from remote hosts in advance of the request to determine which remote host to associate with a session for a client. Each remote host performs a resource calculation (configurable) to determine how many processes/sessions it can further accommodate. The remote host sends the results of the resource calculation and other determined resource information to the session manager. The session manager provides the determined remote host to a client device. The client device then directly connects to the determined remote host. A process may be automatically started on the remote host for the client as the user. The session manager may also store and receive information for active and historical processes, remote host status, and remote host configuration.

Abstract: Features and advantages of the present disclosure include a switching regulator and current measurement circuit. In one embodiment, a switching transistor in the switching regulator has a first voltage on a first terminal and a switching voltage on a second terminal. A current measurement circuit has first and second input terminals. A first switch couples the second terminal of the switching transistor to the first terminal of the current measurement circuit when the switching transistor is on, where the second input terminal of the current measurement circuit is coupled to the first terminal of the switching transistor and measurement(s) may be taken. When the switching transistor is off, the first and second input terminals of the current measurement circuit are coupled together, and measurements emulate zero current through the switching transistor.

Abstract: A target member which may be used in conjunction with sporting activities, such as archery, comprising a housing (20, 21) having an outer surface which forms a portion of a target during use, the outer surface having an aperture (18) therein. The target member also comprises a degradable component (22) which is positionable within said housing such that at least a portion of said second component is exposed by said aperture (18). The exposed portion of said degradable component (22) forms part of the target and the degradable component (22) is repositionable upon degradation of the exposed portion through use of the target so as to expose a further portion of said second component (22) by said aperture (18) for further use.

Abstract: The present invention provides a system and method for remotely accessing a client in a client-server system. From a browser, an end user enters a URL containing a machine name and a port number. A listening program at the client listening on that port number establishes communication with the browser and invokes a client agent. The client agent includes conventional client functions as well as APIs that allow the client to interface with both the server and the browser. The client agent then serves an applet to the browser that makes the browser appear to the end user as the client machine. The user can then execute client functions from the browser. Examples of the client functions include backing up and restoring files from the client to/from the server, migrating or recalling files, archiving or retrieving files.

Abstract: A direct downconversion receiver architecture having a DC loop to remove DC offset from the signal components, a digital variable gain amplifier (DVGA) to provide a range of gains, an automatic gain control (AGC) loop to provide gain control for the DVGA and RF/analog circuitry, and a serial bus interface (SBI) unit to provide controls for the RF/analog circuitry via a serial bus. The DVGA may be advantageously designed and located as described herein. The operating mode of the VGA loop may be selected based on the operating mode of the DC loop, since these two loops interact with one another. The duration of time the DC loop is operated in an acquisition mode may be selected to be inversely proportional to the DC loop bandwidth in the acquisition mode. The controls for some or all of the RF/analog circuitry may be provided via the serial bus.

Abstract: In one embodiment, this disclosure describes a frequency synthesizer for use in a wireless communication device, or similar device that requires precision frequency synthesis but small amounts of noise. In particular, the frequency synthesizer may include a phase locked loop (PLL) and an integrated voltage controlled oscillator (VCO). The frequency synthesizer may implement one or more amplitude calibration techniques prior to enabling the PLL. For example, an amplitude calibration unit may be used to selectively activate switched unit current sources within a tail current source of the VCO. In this manner, the amplitude the signal generated by the oscillator can be adjusted without requiring closed-loop amplitude monitoring or control.

Abstract: A radio frequency (RF) driver amplifier system and method that provides linear in decibel gain control is provided. The RF driver amplifier system comprises a linear transconductor receiving an input voltage and providing a controlled current based on input voltage received, temperature compensation circuitry for varying current from the linear transconductor according to absolute temperature, an exponential current controller receiving current varied according to temperature and providing an exponential current in response, and an inductive degeneration compensator receiving exponential current and providing a control current to driver amplifier circuitry, thereby compensating for inductive degeneration due to at least one inductor in the driver amplifier circuitry. Control current passes from the inductive degeneration compensator to the driver amplifier circuitry. Output gain from the driver amplifier circuitry varies linearly in decibels with respect to the input voltage.
