Abstract:
The invention includes providing a display by moving a colorant particle, having an electric charge, inside a channel of a body in a direction that is substantially parallel to a direction of extension of the channel and a direction of incoming illumination rays. The colorant particle can be moved between a position at a bottom of the channel and at a top of the channel by the force of an electric field generated by a charge at the bottom of the channel. The invention can be applied to an analog dot display as well as a digital dot display. The invention covers methods of manufacturing the displays discussed above. The invention is also not limited to covering displays, and also covers at least print media, wherein colorant particles are locked at appropriate locations within the channels, either temporarily or permanently.
Abstract:
A communications apparatus has a housing and a display and includes a first keypad device and a second keypad device. The first keypad device is immovably disposed relative to the housing and the display. The second keypad device is operative for moving to and between an exposed state and a retracted state. When the second keypad device is in the exposed state, the first keypad device is covered by the second keypad device so that the second keypad device is accessible to a user while the first keypad device is inaccessible to the user. When the second keypad device is in the retracted state, the second keypad device is stowed within the housing and the first keypad device is uncovered such that the second keypad device is inaccessible to the user while the first keypad device is accessible to the user.
Abstract:
An antenna assembly is formed as a thin, unitary element with parallel leads laminated to an insulator. The unitary antenna element includes an integral attachment portion for connection to a printed circuit board. The antenna assembly is usable in electronic devices, such as a cordless telephone radio transceiver. A molded cover, which is directly attached to the electronic device rather than the antenna assembly, is provided to encase and protect the antenna.
Abstract:
A dedicated paging system having single button paging, requiring only a single press of a dedicated button on a page base to automatically page a pager associated with the page base. Information associating the page base with the pager is stored in the page base and/or a database maintained by a paging service provider with which the paging system is registered. When the dedicated button on the page base is pressed, the page base automatically calls the paging service provider. The paging service provider strips the caller identification number from the incoming call, uses the number to look up the pager identification number stored in the database, and then uses the retrieved pager identification number to send a page signal to the pager. Additionally, the paging system is automatically registered with a single press of the button. When the button is pressed, the page base automatically calls a clearinghouse. The page base uploads a pager identification number to the clearinghouse, and the clearinghouse downloads a paging service provider access telephone number to a memory within the page base. The clearinghouse stores the pager identification number and the caller identification number of the telephone line the page base is using in the paging service provider database. Where possible, the clearinghouse also uses the caller identification number to automatically access billing information associated with the number and set up a billing account for the paging service.
Abstract:
An ink cartridge carrier for an ink ejection printing apparatus that provides for positively attaching a flexible cable between the control unit and the ink cartridge carrier. The ink cartridge carrier has an integral construction with slots provided on either side of the front frame section for feeding an end of the flexible cable therethrough and engaging the end of the flexible cable. When the flexible cable is so engaged, contacts found on the flexible cable are properly positioned to contact contacts on a mounted ink cartridge.
Abstract:
A mechanism for preventing rattling between a display cover that is pivotable about a chassis includes a first engagement surface associated with a display cover, and a second engagement surface associated with a chassis, the first and second engagement surfaces being slidably rotatable to allow the display cover to pivot about the chassis in a rotational range defined between open and closed positions. The mechanism includes a device for substantially preventing relative axial movement between the first and second engagement surfaces in the rotatable range. An elongated arcuate segment mounted on the first engagement surface mates with a corresponding elongated slot formed on the second engagement surface. The slot may be sized and dimensioned so as to constitute a stop for the positioning projection so that damage can be prevented that would otherwise occur between the liquid crystal display panel and the keyboard.
