An improved opaque computer keyboard cover (10) which covers only the three- or four alpha-numeric rows of the keyboard (12). Function and format keys (12) are not covered which provides a one-size-fits-all design. This configuration eliminates the need to order from 3000 various keyboard cover sizes. This cover is for use in keyboarding instruction and prevents peeking to accelerate user memorization. This cover can also be imprinted with a language option layout or Dvorak keyboard layout thus fully conforming the keyboard layout to one of the 60 or so languages available in the computer operating system keyboard preference options.

In entering text into an electronic device with a keypad having a number of keys, each key represents a plurality of characters. A character is entered by the corresponding key and selected among the plurality of characters by pressing the key a number of times corresponding to the character. To each key is attached, in addition to the plurality of characters, a further, ambiguous character representing any one of the plurality of characters. A key sequence is activated such that an ambiguous character sequence comprising at least one ambiguous character is generated. Possible non-ambiguous character sequences corresponding to the ambiguous character sequence are generated and compared with a vocabulary stored in a memory and comprising character sequences representing words occurring in a given language. Those possible character sequences that match character sequences in the vocabulary are pre-selected. One of the pre-selected character sequences is selected and entered into the device.

A calculator which generally possesses a flat, compact and portable housing construction, and which includes a calculator lid mechanism which pivots a flat cover of the calculator in a predetermined controlled manner between a first position causing the flat cover to form a lid which overlies a calculator display, and a second operational position in which the cover is pivoted towards the rear of the calculator so as to form a stand for tilting the calculator into an upwardly inclined ergonomic position relative to a horizontal support surface during intended use thereof. Upon the actuation of a switch, a release mechanism enables the lid to be pivoted rearwardly in a controlled damped manner about a hinge connection, which articulates the lid to the calculator housing, under the urging of a torsion spring and damping drum arrangement constituting the lid mechanism located within a tubular bore within the hinge portion of the lid structure into an essentially perpendicular orientation relative to the rear surface of the calculator housing so as to form the stand for tiltingly support the calculator when positioned on a horizontal surface.

The specification and drawings present a new method and apparatus for a touch actuation in an electronic device using a general purpose input board. The input board comprises of a grating of conductors running in one direction (y-lines). Between these conductors there are contacts connected to a grating running in the perpendicular direction a layer below (x-lines). The grating layers are separated by an insulating layer. Various known methods can be used to read the position of, e.g., a conductive actuator touching the input board. The input board can be used as a configurable UI board under a keymat. The input devices on the keymat can be a key, a joystick, a touchpad top membrane, etc. Also, the actuators can be made force-sensitive by detecting a contact surface area. In addition, all components of the general purpose input board can be made of materials substantially transparent to light.

Disclosed herein is a light guide plate for keypad backlight panels, which is mounted at the rear of a keypad having numerals or characters printed thereon for supplying light emitted from a light source mounted at one side of the keypad to the keypad. The light guide plate is made of polycarbonate and is provided at the rear surface thereof with a concave-convex pattern, the density of which is increased as pattern elements of the pattern become more distant from the light source, such that light emitted from the light source is reflected and is uniformly supplied to the keypad, the pattern being formed on the light guide plate by hot stamping, injection molding, or micro blasting. The density of the pattern is adjusted by adjusting the distance between the pattern elements of the pattern or by adjusting the size of the pattern elements of the pattern. Consequently, it is possible to manufacture a keypad module in a slim structure or a curved structure. It is also possible to manufacture a keypad module that is capable of uniformly supplying light.

A method of data communication. The method includes transmitting a control message identifying missing data as lost by the transmitter prior to the expiration of a timer. The missing data may include at least one data packet such that the control message identifies the at least one missing data packet. The control message may include a field and/or an acknowledge sequence number for identifying the missing data packet. The control message also may include a packet data unit having a dummy payload and/or a zero payload. The control message communicates to the receiver that the transmitter has aborted the transmission and/or retransmission of the one or more missing data packets. The control message may be communicated to the receiver over the same data channel used for transmitting the data packets, or alternatively, a wholly different channel than the data channel.

A plurality of packets are received at a receiver. The plurality of packets are sent in a first ordering from a transmitter and received in a second ordering. The second ordering is different from the first ordering. The packets, when they were sent, are assigned sequence numbers based on the first ordering. As each of the plurality of packets is received in the second ordering, a packet is written to a buffer position in a buffer based on the sequence number associated with the packet. The writes to the buffer positions are out of order or in a non-sequential order as compared to a sequential ordering of buffer positions in the buffer. Packets are then read from the buffer in a sequential order. As packets are read from the buffer, they are read in the first ordering that the packets were sent in.

An improved key matrix scanning technique conducts a first pre-scan on a first array of connections in a key matrix to identify any activated keys or buttons associated with the first array. A second sub-scan is conducted on a second array of connections in the key matrix but only for the connections in the first array that are detected as having activated keys.

An electronic digital controller, such as a load cell indicator, is disclosed in which a number of components, such as a circuit board, display, and keypad are placed within an enclosure, and the enclosure is bonded closed, such as using an adhesive, to render the enclosure watertight. The keypad is a touch sensitive, capacitive keypad with no moving parts, and it is housed behind a rigid panel. An optoelectronic transceiver allows for data exchange with an electronic memory device housed in the adhesively sealed enclosure and allows for data exchange and for updating or modification of software code housed therein. Other components, such as another circuit board, a power supply, and block connectors, are placed in an adjacent enclosure, and the circuit boards in the two enclosures are electrically connected. The power supply is preferably a potted AC power supply but may also include a battery.
