Abstract: A method of transferring images from a first device to a second device and computer program code for performing this method is described. A connection characteristic for a connection between the first & second devices is determined and at least one image is selected from a plurality of images on the first device for transfer dependent upon both the connection characteristic and image selection criteria. The selected image(s) are then transferred over the connection from the first device to the second device.

Abstract: A surface computing device is described which has a surface which can be switched between transparent and diffuse states. When the surface is in its diffuse state, an image can be projected onto the surface and when the surface is in its transparent state, an image can be projected through the surface and onto an object. In an embodiment, the image projected onto the object is redirected onto a different face of the object, so as to provide an additional display surface or to augment the appearance of the object. In another embodiment, the image may be redirected onto another object.

Abstract: Collapsible tables are not sturdy or attractive, whereas tables with these properties are not easy to store or transport. Thus there is a need for a table which is simultaneously attractive, sturdy, and easy to move or store. According to one aspect of the invention, a table is provided that has legs that fold and nest. The legs are held in the open position by one or more mechanical rotating clasps. According to another aspect of the invention, table is provided that has legs that fold in pairs. When in the folded position, one pair of legs nests within the other pair.

Abstract: A method of displaying digital images is described in which a display length indicator is received and digital images are accessed. A set of digital images are selected from the accessed digital images in accordance with the display length indicator and displayed in a predetermined order. The method may be performed by a computer program, which may be embodied on a computer readable medium.

Abstract: A method of compiling source code is described in which symbol information is retained in the optimized object code and the executable file. This symbol information is retained in the form of function calls which return memory locations and enable an application to query where variable or function data is stored and then access that variable or function data.

Abstract: A pump assembly including a gerotor pump having an inlet and an outlet, and comprising an annulus and a lobed rotor, one, but not both, of the rotor or annulus being split axially into two parts, the pump further comprising indexing means for angularly shifting one part relative to the other part, the indexing means comprising a chamber having a first indexing port and a second indexing port, and a partition which divides the chamber into a first portion including the first indexing port and a second portion including the second indexing port, wherein the partition comprises a part which is pivotally mounted within the chamber for angular movement within the chamber.

Abstract: Methods of controlling the transfer of data between devices are described in which the manner of control is determined by a movement experienced by at least one of the devices. The method involves detecting a triggering movement and determining a characteristic of this movement. The transfer of data is then controlled based on the characteristic which has been identified.

Abstract: A device is described which changes its operation dependent upon the location of the device. The device accesses parameters which are specific to its location and uses these to determine how the operation of the device should be changed.

Abstract: A touch panel is described which uses at least one infrared source and an array of infrared sensors to detect objects which are in contact with, or close to, the touchable surface of the panel. The panel may be operated in both reflective and shadow modes, in arbirary per-pixel combinations which change over time. For example, if the level of ambient infrared is detected and if that level exceeds a threshold, shadow mode is used for detection of touch events over some or all of the display. If the threshold is not exceeded, reflective mode is used to detect touch events. The touch panel includes an infrared source and an array of infrared sensors.

Abstract: A touch panel is arranged to enable communication using infrared signals with nearby devices. The touch panel includes an array of infrared sensors, arranged parallel to the touchable surface of the panel and at least one of the sensors is capable of detecting an infrared signal received from a nearby device.

Abstract: The invention is directed to a space reservation system that has the ability to receive occupancy information relating to a space. The occupancy information originates from a sensor. The invention is also directed to an occupancy sensing apparatus for a space reservation system. The sensing apparatus includes a sensor and a processor that determines from the data from the sensor whether the space is occupied. This information can then be sent to a space reservation system. The invention is also directed to a method of reserving a space in which the occupancy of the space is detected and if the space is occupied, a reservation is made for the space for a period of time.
