Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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).
Abstract:
A wireless subscriber communication unit comprises a transmitter having a power amplifier and a feedback power control loop having a power control function arranged to set an output power level of the power amplifier. The power control function is arranged to perform a back-off of the output power prior to completion of a transmission burst.
Abstract:
Articles for applying color on a surface comprise a sheet of dry color component and an adhesive on one surface of the sheet of dry color component. The article further includes a releasable liner, and the sheet of dry color component is arranged between the releasable liner and the adhesive. Methods for providing a substantially permanent color effect on an architectural surface comprise delivering such an article to the architectural surface.
Abstract:
Embodiments of the present invention address deficiencies of the art in respect to inbox management in a messaging system and provide a novel and non-obvious method, system and computer program product for inbox management for threaded message views. In one embodiment, an inbox management method for threaded message views can be provided. The method can include selecting a message in a message list for an inbox, identifying a message thread for the selected message, retrieving all messages for the message thread, and inserting a listing of the retrieved messages for the message thread in the message list.
Abstract:
A system and method allowing a session initiator to select from among multiple privacy levels to be applied to an instant messaging session. When a user initiates an instant messaging session, multiple selectable privacy settings are presented, from which the user can select. The disclosed system may provide a session initiator with a user interface that enables selection from among privacy settings that prevent the session contents from being copied and pasted while the session is in progress, prevent any saving of the session contents by any user, prevent the session contents from being forwarded via electronic mail, prevent display of previously viewed session contents while the session is in progress, and/or prevent screen shots from being made of the session contents while the session is in progress. Flags representing one or more of the multiple privacy settings may be stored in association with an ongoing session, and/or in association with the stored contents of a previous session. In one embodiment, only the session initiator can select from among the multiple privacy settings, and may be provided with indication in the user interface of the privacy settings that are supported by individuals listed in their buddy list.
Abstract:
A tire composition is provided that may include a sulfur-functional linear polyorganosiloxane and an unsaturated elastomer. The sulfur-functional linear polyorganosiloxane may include a chemically protected sulfur group, which includes a thiocarbamate, a dithiocarbamate, or a derivative or analog of thiocarbamate or dithiocarbamate. Under certain conditions, the sulfur group may react with the unsaturated elastomer. The invention includes embodiments that may relate to methods of making and using the sulfur-functional linear polyorganosiloxane in tire compositions.
