A wireless communication system having a terminal unit operates in a reduced noise state during receipt of a wireless transmission from a control unit. The terminal unit includes terminal circuitry, a radio and noise management circuitry. The noise management circuitry partially or fully disables operation of the terminal circuitry during a receipt by the radio. Noise management circuitry may disable a terminal processor, disable interrupts, buffer interrupts and otherwise modify operation of the terminal circuitry to reduce generated radio noise that would otherwise interfere with receipt of data by the radio. The wireless communication system includes noise management circuitry located in a control unit that operates in conjunction with noise management circuitry in a first terminal unit and a second terminal unit to schedule transmissions from the control unit. These scheduled transmissions allow the terminal units to perform required processing functions outside of the reduced noise period.

Wireless communications system having reduced noise mode operation capability

A portable hand-held data terminal having a curvilinear cross-sectional keypad capable of operation by one hand. In an exemplary embodiment of the invention the keys may extend to various heights above the keypad depending on their function. For example, a scan trigger key may extend the farthest from the terminal, numeric keys may extend the next farthest, and alphabetic keys may extend the least. The data terminal may also provide a quick release pistol grip to terminal attachment which utilizes, in an exemplary embodiment, a pair of removably receivable compressible O-rings, a pair of removably receivable guides, and a lever-type latch mechanism. The invention may also provide an interface between the pistol grip assembly's trigger mechanism and the data terminal which does not require that the housing of the data terminal be pierced. In an exemplary embodiment this interface utilizes a reed switch, mounted inside the data terminal's housing, and a magnetic trigger assembly wherein the reed switch is held closed by the magnet when the trigger is depressed.

Ergonomic hand-held data terminal and data collection system

In an exemplary embodiment, portable data devices can be coupled with a local area network at any of a multiplicity of points and integrated into the system. The preferred system is highly flexible and closely adaptable to changing needs of an individual user. For example, unitary multiple docking devices each receiving a plurality of hand-held computerized data terminals may be chained in a series to a single primary controller which may have a further LAN channel including an auxiliary unit which may supply charging power to a further series of multiple docking devices, added to the system as needed. A preferred auxiliary unit is capable of handling two-way communication without the provision of a direction control line in the channel. A preferred LAN system may have unitary printed circuit boards or other rigid network pathways provided with multiple docking receptacles. The control for the LAN system will automatically establish identities for randomly added devices.

System having plurality of docking unit receptacles for transmitting

In an exemplary embodiment, portable data devices can be coupled with a local area network at any of a multiplicity of points and integrated into the system on a dynamic basis. The preferred system is highly flexible and closely adaptable to changing needs of an individual user. For example, unitary multiple docking devices each receiving a plurality of hand-held computerized data terminals may be chained in a series to a single primary controller which may have a further LAN channel including an auxiliary unit which may supply charging power to a further series of multiple docking devices, added to the system as needed. A preferred auxiliary unit is capable of handling two-way communication without the provision of a direction control line in the channel.

Data communication system for assigning addresses to hand-held data

A terminal for receiving and storing information and a reader for reading information and communicating the information to the terminal. A housing is provided which has the terminal and reader integrated therein and also a battery for providing necessary power thereto. A detachable handle can be attached to the housing and includes sides which extend around the sides of the housing as well as partially extending over the top of the housing. An improved mechanism is shown for selectively locking a handle to a terminal. A holster for holding the terminal and handle is also shown. A handle with a scanner integrated therein is attachable to a terminal for receiving and storing information read by the scanner.
