Abstract: An enhanced manner of datacasting and providing broadcast television to portable devices is disclosed, including tuner assistance, improvements in recording and datacasting content, and assisting users in obtaining the optimum experience from their set-up. A small form factor, low cost accessory product such as a WiFi dongle with one or more tuners can be used to provide the single function of delivering content to portable devices. The content can be sourced from broadcast (e.g. ATSC/DVB-T, etc.) and can be in the form of live (linear) television or download (on demand) programming. No Internet connection is required.

Abstract: A place-shifting system for distributing video content from a content source (2) has apparatus including a set-top box (STB) (1) with a digital interface to a sender (6). The sender (6) receives video content from the STB (1) conditional upon access permissions that may be associated with a subscription. The permissions may also be determined using the identifier of a viewer device (9). The viewer (9) requests connection to a specific sender (6) by sending an association request to an association server (8) via a network connection (10). The association server (8) returns location information specific to the sender (6) being requested to the viewer (9). The viewer (9) and sender (6) then communicate directly (11) to establish communication and to start transfer of video and other information. The sender (6) can remove content protection from the video content before transcoding, re-applying content protection and sending it.

Abstract: This invention relates to a MEMS detonator, in particular the production of MEMS scale detonators via the use of a microreactor (3). The invention further lies in a reproducible manufacturing method of MEMS scale detonators, for use in safety and arming units (SAU), which are used in warheads and munitions. A warhead comprising a MEMS detonator may find particular use in increasing the IM compliance of munitions. The method involves the use of high pressure input of two solutions (2, 2a) into a microreactor (3) to form an in-situ precipitation reaction, which furnishes an initiatory (i.e. primary) explosive, wherein the explosive and supernatant liquid is directly fed into a microchamber, using the microcavities in the septum as a MEMS sieve to retain the explosive and form a MEMS detonator.

Abstract: A molecular single electron transistor (MSET) detector device (14) is described that comprises at least one organic molecule (87) connecting a drain electrode (84) and a source electrode (82). In use, said at least one organic molecule (87) provides a quantum confinement region. At least one analyte receptor site (90, 92) is provided in the vicinity of said at least one organic molecule (87) that bind molecules of interest (analytes). A fluid analyser (2) is also described that includes the MSET detector, a pre-concentrator (4) and a fluid gating structure (6). The fluid gating structure (6) is arranged to selectively route fluid from the pre-concentrator (4) to either one of the detector (14) and an exhaust port (12). The pre-concentrator (4), fluid gating structure (6) and detector (14) are each formed as substantially planar layers and arranged in a stack or cube.

Abstract: A device for detecting infrared radiation is described that comprises a resonator element (36; 72; 96; 120) fixably attached to a supporting frame (32;130). The supporting frame (32;130) is arranged to absorb infrared radiation received by the device. The resonator element (36; 72; 96; 120) has a resonant property, such as resonant frequency, that varies with temperature. The device may comprise a plurality of detection elements (70), each detection element comprising a resonator element (72) fixably attached to a supporting frame. A thermal detector array device may also be provided.

Abstract: A micro electromechanical system (MEMS) switch includes a fixed contact (24) and a moveable contact (35) on an armature (30). The switch has electrodes (22, 34) associated with both the fixed and moveable contacts for providing an electrostatic switch operation and piezoelectric material with associated electrodes (36, 40) for bending the armature upon application of an electric voltage and providing an initial piezoelectric switch operation followed by electrostatic switching and clamping. The armature is of curved shape which is bent away from the fixed contact when in a switch open condition with zero applied voltage. This gives a large, e.g. 3 pm, switch gap in an OFF state which is reduced by piezoelectric operation suitable for electrostatic switch closing. A curved condition is provided by varying strain across the armature thickness, and is produced during manufacture of the switch.

Abstract: An optical routing device is described that comprises a semiconductor substrate (52) having at least one optical input (4), a plurality of optical outputs (6,8) and an array of MEMS moveable reflective elements (58;102). The array of moveable reflective elements (58;102) are configurable such that light can be selectively routed from any one optical input (4) to any one of two or more of said plurality of optical outputs (6,8). Light selectively routed from any one optical input to any one of two or more of said plurality of optical outputs (6,8) is guided within a hollow core waveguide (54). In one embodiment, a cross-connect optical matrix switch is described.

Abstract: A variable optical attenuator device is described that comprises a first optical input, a first optical output, a first optical path between the first optical input and the first optical output, and means for moving a shutter across said first optical path. A hollow core waveguide is provided to substantially guide light along the first optical path of the device. The device may also be used to provide an analogue beam splitting or switch function in telecommunication systems and the like.

Abstract: An electronic safety and arming unit comprises a micro electromechanical system (MEMS) shutter device. The shutter (18) is suspended by thin lightweight arms and hinges, all formed by silicon processing of SOI substrates and includes holding latches for holding the shutter (18) in the closed position. The holding latches may be released by an electrothermal actuator. The shutter (18) separates an initiator section from an explosive train (6) of munitions such as shells, thereby providing safety until the shell is fired and away from its start point. After firing, the shutter (18) is opened ready for the main explosive to be detonated by the initiator (3). The shutter (18) may be suspended by a compliant displacement multiplier and may include an electrothermal actuator such as an electrically heatable bent beam. Heating of the beam causes movement of a shutter blade from a shut condition covering a firing aperture to an open condition.

Abstract: A disk drive comprises a magneto-resistive read head and an inductive write head for use with removable hard disk cartridges. A four-burst embedded servo is written and read to guide the servo-positioning of the magneto-resistive read head over data tracks recorded on the removable hard disk.
