Abstract:
An improved position sensing controller (40) allows a person to precisely control the movement of a remote object or device in one or two dimensions by simply tilting the hand-held controller (40) to generating control signals. A position sensor (48a) that includes a bubble (56) in a liquid is used to determine the angular position of the controller with respect to a horizontally level plane. A light source (64) emits light that is reflected by the bubble, into two opposing photodiodes (68a, 68b). A ratiometric amplifier (80) produces a signal corresponding to the ratio of the light incident on each of the photodiodes (68a, 68b) to provide a signal corresponding to the angle, relative to a horizontally level plane, by which the controller is tilted. The controller (40) can use a diffused laser light-emitting diode to transmit signals to the controlled device.
Abstract:
The method for running a process in a host device having one embodiment of an auto-start driver in the host device detects insertion of a storage media into a peripheral (341), searches for a file of a predetermined name in the storage media (351), and automatically starts an application listed in instruction in the file (362). Another embodiment of the auto-start driver looks for a file of the predetermined name in the host device's permanently installed storage media prior to searching in the inserted storage media (347). When a previously inserted removable storage media is removed from the peripheral, the auto-start driver ends the started application (351), restores the operator interface screens to a state existing prior to insertion, and releases portions of random access memory that were used by the ended application (353). In another embodiment the auto-start driver can automatically copy a new version of auto-start driver software (378) or other new software (386), such as word processors into the permanently installed storage media.
Abstract:
A remote control (10) for an interactive media can include a printed publication (11) and/or a storage media (13) and/or a data button (12). One embodiment of a remote control (100) includes a printed publication (101), such as a book, magazine or a catalog, and one or more buttons (104) physically attached to the printed publication (101) to allow users to remotely control use of associated electronic content by a host device (120). Another embodiment of a remote control (110) has a housing (118) capable of removably holding a storage media (119) encoded with electronic content associated with a button (114) of the remote control (110). Yet another embodiment of a remote control (400) has at least one data button (402) which permits the user to select the data to be displayed by the host device (420). An autostart driver (436) in the host device (420) detects insertion of a storage media (428M, 432M) into a peripheral (428, 432) and automatically starts an application (437). The application (437) interprets button codes transmitted by the remote control (400) and displays the results or initiates other events.
Abstract:
A controller has a light source (102) and a photosensitive element (101, 103). The controller also includes a flexible element (107) having a first shape and located adjacent to substrate (104) opposite to light source (102) and photosensitive element (101, 103). Flexible element (107) transfers a first portion of light from light source (102) to photosensitive element (101, 103). On application of a force to flexible element (107), flexible element (107) deforms elastically from the first shape into a second shape. In the second shape, flexible element (107) transfers a second portion of light to photosensitive element (101, 103). On cessation of application of the first force, flexible element (107) reverts back to the first shape, and so transfers the first portion of light to photosensitive element (101, 103). The portion of light transferred by flexible element (107) in the second shape depends on the deformation of flexible element (107), and can be calibrated to measure the amount of such deformation.
Abstract:
In accordance with this invention, a novel stick-on peel-off fastener (201), comprising one or more conductive sticky elements (204, 205), sandwiched between one or more terminals (256, 257) of a first object such as an electrical device (250) and one or more terminals (206, 207) of a second object such as battery (202), can keep the battery (202) affixed to the electrical device (250) while the battery (202) supplies power to the electrical device (250). One embodiment of a conductive sticky element includes a layer of conductive adhesive (204, 205), such as a polymer resin that has a number of microscopic silver filings. Another embodiment of a conductive sticky element (304, 305) includes a number of hooks, such as those in Velcro elements. Yet another embodiment of a conductive sticky element (404, 405) includes a magnet that when used with another magnet (454, 455), prevents improper coupling of the two objects (400, 450) due to magnetic repulsion.
Abstract:
A ratiometric sensor (210) is formed of a first photodiode (212) connected in series with an electronic component, such as a second photodiode or a resistor (211), between a source of a first voltage and a source of a second voltage. The ratiometric sensor supplies a "ratiometric voltage" on a ratiometric sensor output line that is connected to a junction between the first photodiode and the electronic component. The ratiometric voltage is proportional to the ratio of the equivalent resistance of the first photodiode to the sum of the equivalent resistance of the first photodiode and the electronic component. A ratiometric sensor that uses a photodiode and a resistance has a large dynamic range because the ratiometric voltage can vary between the first voltage and the second voltage. A ratiometric sensor that uses two photodiodes is less sensitive to noise than a conventional circuit that uses a single photodiode, because noise can get cancelled from the numerator and denominator of the ratio. The ratiometric signal can be digitized by an analog-to-digital converter that can include, for example, a 555 timer, a Darlington transistor or a combination of a resistor and a capacitor.
Abstract:
A position sensing controller (110), sometimes referred to as "controller" includes a novel optical gate (114) that is located adjacent to a light source (125) and to a light sensor (116, 117). The optical gate (114) changes the amount of light incident on the light sensor (116, 117) in response to a change in position of a movable element in the controller (110). The position signal can drive any electrically controllable device, such as a game machine, a personal computer and an interactive television set top. The use of optical principles in a position sensing controller allows various optical position sensing parts of the controller, such as the light source, the light sensor, and the optical gate to be physically separated from each other and so avoid the mechanical wear and tear caused by friction in conventional controllers.
