Abstract: Systems and methods for emulating a channel for wireless communications between a transmit (TX) system-under-test (SUT) and a receive (RX) SUT. The TX and RX SUTs include integrated antenna arrays for transmitting and receiving wireless signals. For a plurality of paths of the emulated channel, and for each antenna element of the TX SUT, a respective phase shift and gain modification is applied to a wireless signals transmitted by the respective antenna element. The phase shifts and gain modifications emulate path length differences between different antenna elements. The signals for each antenna element are summed, and a path-specific modification is applied to each aggregate signal for each path. For each RX antenna element, phase shift and gain modifications are applied to emulate path-length differences for the RX antenna elements, the resultant signals are summed for each path, and the emulated wireless signals are output to the RX antenna elements.

Abstract: A system and process are disclosed for providing users with page previews during page loading events, such that the delay experienced before the display of page content is reduced. The previews may include screenshots of the pages or of portions thereof, and may be generated periodically and cached by the system for delivery to user devices. The process of generating and delivering the previews via the Internet or some other network may be implemented partly or wholly within an intermediary system that sits logically between the user devices and content servers. The process may be used with existing browsers without the need for any browser modifications, or may be used with a “preview-aware” browser that includes special program code for providing page previews.

Abstract: Features are provided for facilitating prioritized transmission of content between content providers and content requesters. A content provider or intermediary entity obtains prioritization rules for transmitting network resources, such as resources embedded in or otherwise associated with web pages. The prioritization rules can be general rules applying to the transmission of all network resources or a large number thereof, or they can be customized for a specific network resource or small group thereof. The prioritization rules can be applied to the relative bandwidth utilization or data transfer rates of network resources. The relative bandwidth utilization or data transfer rates can be adjusted in response to network or user events.

Abstract: Apparatus for determining the pulse width of ultra-short light pulses of an input repetitive light pulse signal comprises a two-photon absorption detector (2) in the form of a microcavity (3) having an active region (4) located between top and bottom distributed Bragg reflectors (5,6). An optical fibre cable 16 directs the input light pulse signal combined with a reference repetitive light pulse signal normal to an incident surface (8) of the detector (2). The input light pulse signal is split in a polarisation light splitter (19) to form the reference light pulse signal which is passed through a delay line (23) to a polarisation light combiner (20) to be combined with the input light pulse signal, and directed at the incident surface (8) by the optical fibre cable (16). The delay line (23) is operated for alternately bringing the respective light pulses of the input and reference light pulse signals into and out of phase with each other to produce a pulsed photocurrent in the microcavity (3).

Abstract: Information relating to the characteristics of the documents contained in a document cassette 16 is stored in a button memory 22 on the cassette housing and is read when the cassette 16 is inserted into a document feeding apparatus. The information is processed and correlated with data stored in the memory 74 of a control unit 70 to determine the optimum settings for a mechanism 10 for picking such documents. In particular, during a pick operation, a predetermined number of pulses are supplied to a stepper motor 50, so that when the friction belt 30 is moved into engagement with the documents of the cassette 16, an optimum pressure is exerted by the belt 30 on the documents in the cassette 16. A retard roller 52 is then moved to an optimum position in relation to the belt 30.

Abstract: A belt (28) is moved into contact with a sheet (70) to be fed from the stack (18) under the control of a solenoid (48), which when energized causes pivoting of a crank mechanism (42) and an pulley (26) which supports the belt (28). The belt (28) frictionally engages the sheet (70) as to separate it from the stack (18) and move it into engagement with feed rollers (56) of a transport mechanism. The belt (28) is then retracted from the sheet (70) which is moved away from the stack (18) by the feed rollers (56). After a predetermined time period, the belt (28) is moved into contact with the next sheet of the stack (18) to be fed and the process is repeated until the desired number of sheets have been fed from the stack (18). The belt (28) is driven so that it rotates continuously during the pick operation and is brought to rest on retraction of the belt (28) after the final sheet has been picked from the stack (18).

Abstract: The apparatus for ultrasonic tissue investigation comprises an ultrasonic transducer (1) adapted to emit pulsed emissions into tissue and means (2) to move the transducer to scan an area of tissue to be investigated. Signals reflected from interfaces between acoustically different tissue components are received and converted into a representation of the tissue, which may be visually displayed. The emissions of ultrasonic radiation are so pulsed that each pulse has a very rapid fall back period, enabling better discrimination. Interpretation of the images may be facilitated by use of such techniques as fractal analysis.

Abstract: A belt displacement operation is periodically carried by the pick mechanism 11 of a sheet feeding apparatus, when the number of sheets fed has reaches a predetermined value. The motor 34 is driven in reverse for a predetermined time, so as to cause rotation of the belt 28 in the opposite direction to that during feeding. Since the pick pulley 26 is supported on the shaft 38 by means of a one-way clutch 40 so that it does not rotate during the reverse rotation of the belt 28, displacement of the belt 28 occurs relative to the pick pulley 26, so that in subsequent pick operations, a different portion of the belt 28 engages the stack 18 so as to pick a sheet, than had displacement of the belt 28 not occurred. This reduces the risk of localized portions of the belt 28 becoming more worn than others, due to more frequent engagement with the stack 18.

Abstract: A self service financial print terminal (10) has a keypad (14) to input instructions; a card reader (44) to read a data-bearing user card; and a printer (20) to print a financial document such as a cheque in accordance with instructions. A correctly-printed cheque is driven by pairs of rollers (22,24) to a delivery slot (18). An incorrectly-printed cheque is diverted by divert mechanism (30) to pass between a pair of print rollers (34) which print a stripe on the cheque in indelible security ink. The marked cheque can then be retained in a non-secure part of the terminal (36).
