    摘要: A wireless communication unit comprises a transmitter having a forward path comprising a power amplifier, PA, and a feedback path operably coupled to the power amplifier, wherein the feedback path comprises a coupler arranged to feed back a portion of a signal to be transmitted and a controller logic module arranged to control a power control value of the power amplifier, such that the forward path and feedback path form a closed loop power control. The controller logic module is arranged to determine a gain variation in the transmitter and provide attenuation to a transmit signal passing therethrough on a transmit slot by transmit slot basis and instruct a power backoff where necessary.

    摘要: A file format that includes a constant section and a varying section. The constant section provides a referencing scheme that references the various components that comprise the scene, as well as a listing of attributes of the scene that are modifiable. Within the same file format, the varying section provides an overriding mechanism to modify the attributes that are available to be modified. Accordingly, the disclosed file format can access cached animated geometry directly and/or aggregate other files via the aforementioned referencing and sparse override semantics. This allows the same set of inspection, manipulation, and rendering tools to be used throughout the rendering pipeline, from asset creation to final rendering.

    摘要: Fiber optic collimators are disclosed for use in fiber optic rotary joints (20) providing for improvement in insertion loss performance. One embodiment of the fiber optic collimator has a gradient-index rod lens (61) possessing a pitch of less than one-quarter. Improvement in insertion loss arises due to the increase in the effective focal length of the lens as the pitch is reduced, allowing the collimator to achieve a longer working distance. The increase in the effective focal length is accompanied by an increase in the back focal length of the lens, compared to the zero back focal length of the more typical quarter-pitch gradient-index rod lens. The increased back focal length can be filled by a cylindrical glass spacer (64), to which an optical fiber (68) is attached, resulting in a collimator with very similar form factor to the usual quarter-pitch gradient-index rod lens collimator. The increased back focal length can also be filled by a form of right-angle prism (71), to which an optical fiber is attached such that the fiber is oriented at 90 degrees to the optical axis of the lens useful for applications of pancake-style hybrid slip rings wherein the desired direction of fiber ingress to the rotary joint is perpendicular to the rotation axis of the rotary joint.

    摘要: A storage and drinking container for pressurised beverages comprises a drinking vessel (1) having a lip (3) and a lid formed from a cap (5) and retaining ring (12). The cap (5) seals with a sealing surface (4) on the inside of the neck of the drinking vessel and is retained in place by fingers (8) engaging under a lip (3). The fingers 8 are retained in position by a retaining ring (12). Cooperating sets of cammed surfaces (10) and (13) on the cap (5) and retaining ring (12) act on rotation of the retaining ring to axially separate the retaining ring (12) from the cap (5), releasing the fingers 8 from under the lip (3) and permitting the lid to be removed. The invention provides a drinking vessel with a wide neck which can be reliably sealed without the necessity to provide screw threads on the outer surface of the drinking vessel (1).

    摘要: An apparatus and method for controlling the common mode voltage across a data storage device write head. The write current is supplied by a first plurality of parallel current sources each independently activated to limit the common mode voltage generated across the write head. A plurality of parallel resistive elements responsive to current supplied by a second plurality of parallel current sources bias an output transistor that further controls the write current. Each of the plurality of parallel resistive elements and each of the second plurality of parallel current sources is also independently activated to limiting the common mode voltage generated across the write head.
