Described is a filtering mechanism/process that selectively controls whether graphics primitives are provided to a given driver. For example, graphics primitives of an accessibility (e.g., magnification) program may be excluded from being obtained by mirror drivers associated with the accessibility programs, so that the mirror drivers receive only the primitives of unmagnified windows. A registration mechanism allows a program to identify its window as being associated with a class of drivers for filtering, and the drivers may identify themselves as being of the class. By maintaining data that associates windows with a class of drivers, when graphics primitives associated with a registered window are received, a filtering operation be activated to determine which graphics primitives are provided to which driver or drivers. Filtering may be by exclusion to prevent certain primitives from being obtained by excluded drivers, or by inclusion whereby only included drivers receive certain primitives.

Described is the selective exclusion of content returned in a requested screen capture operation, wherein exclusion may be determined by a window category and the requesting application program. For example, a magnification program will not received content captured from its own layered window or from any other layered magnification windows. A registration mechanism obtains and maintains a window handle for any window registered for exclusion. A screen capture mechanism uses the information to determine whether to exclude the content of windows when returning the captured screen content. Exclusion may be accomplished by enumerating areas that are not covered by any layered window and copying those areas to a screen representation buffer or the like, and separately enumerating areas that are covered by at least one layered window. A covered area is only copied to the screen representation when it does not correspond to an excluded window.

Described is a technology including a mechanism a mechanism that when activated, detects a call to a device independent bitmap. An appropriate mirror driver, such as one or more registered as an accessibility driver, may then be notified of the call. The mechanism may be activated upon creation or selection of the device independent bitmap, and may comprise a wrapper/driver that, from the perspective of the mirror driver, simulates a call to a device dependent bitmap. The notification may be performed by having the driver communicate a function call that emulates a drawing primitive to the mirror driver.

A method for dynamically configuring a video stream, including: identifying player control metadata attributes for an input video stream, wherein the input video stream is received from an origin server; storing the identified metadata attributes to a memory device; and dynamically inserting the metadata attributes into an output video stream in real-time.

This invention relates to the use of one or more cannabinoids in the treatment of epilepsy and more particularly to the use of one or a combination of cannabinoids in the treatment of generalized or partial seizure. In one embodiment it relates to the use of the cannabinoid THCV, as a pure or isolated compound, or as a plant extract in which significant amounts of any THC naturally present has been selectively removed. In another embodiment the phytocannabinoid is CBD.

Systems and methods for downloading algorithmic elements to a coprocessor and corresponding processing and communication techniques are provided. For an improved graphics pipeline, the invention provides a class of co-processing device, such as a graphics processor unit (GPU), providing improved capabilities for an abstract or virtual machine for performing graphics calculations and rendering. The invention allows for runtime-predicated flow control of programs downloaded to coprocessors, enables coprocessors to include indexable arrays of on-chip storage elements that are readable and writable during execution of programs, provides native support for textures and texture maps and corresponding operations in a vertex shader, provides frequency division of vertex streams input to a vertex shader with optional support for a stream modulo value, provides a register storage element on a pixel shader and associated interfaces for storage associated with representing the “face” of a pixel, provides vertex shaders and pixel shaders with more on-chip register storage and the ability to receive larger programs than any existing vertex or pixel shaders and provides 32 bit float number support in both vertex and pixel shaders.

A structural support column with telescopically adjustable head, includes a base, and an elongate support member extending substantially vertically from the base. The support member has a remote end opposed to the base with a cavity. A centralizing member covers the cavity at the remote end of the support member. The centralizing member has an aperture which is axially aligned with the longitudinal axis of the support member. A levelling screw is provides having a first end with a head and a second end. The second end of the levelling screw extends through the aperture in the centralizing member and is secured against removal by a levelling nut. The first end of the levelling screw is received in the rectangular cavity at the remote end of the support member. The head at the first end of the levelling screw is received in close fitting engagement in the cavity. A support bracket is positioned at the second end of the levelling screw.

An optical reflectometer in which the output from a laser 11 is passed through a ramped phase modulator 12 and an optical fibre bi-directional coupler 13 to a transmission path 15, e.g. an optical fibre. Part of the light is coupled out to a mirror 14 and is reflected to form a local oscillator signal which is mixed in the coupler with backscattered light from the fibre. The mixed signals are applied to a detector 16.

A strain sensor providing an optical read-out that is suitable for use in electrically noisy environment or one subject to mechanical vibration consists of one or a set of single mode optical fibres wound round an expanding strain member. The principle of operation relies upon the fact that transverse straining of a single mode fibre destroys mode degeneracy thereby producing birefringence effects that can be rendered obversable using polarized light and a polarization analyzer.

A method may include receiving, from a network, a call request in a communication device, the call request including an identification of a calling party; notifying a user of the communication device of the call request; receiving an indication to deny the call request; prompting the user of the communication device, in response to receiving the indication to deny the call request, regarding automatically denying call requests having the identification of the calling party; receiving, from the user, an indication to deny call requests having the identification of the calling party; and sending an instruction to the network to automatically deny the call requests having the identification of the calling party.
