  • Patent number: 6144976
    Abstract: A portable data collection terminal has an elongate housing with a hand grip conforming rear surface. A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys of the numerical keyboard are identified by indicia disposed on a template. The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template.

  • Patent number: 6075780
    Abstract: A transceiver apparatus for creating a wireless personal local area network between a computer terminal and one or more peripheral devices. A separate transceiver is connected to the computer terminal and to each peripheral device. The transceivers can be connected to the terminal or peripheral device either internally or externally. A low power radio is used to communicate information between the computer terminal and peripheral devices. Different transceivers can be used for modifying the carrier frequency and power of the local area network. The microprocessor is located inside each transceiver and controls the information flow of the transceiver including the communication protocol which allows each device to know if other devices are communicating, which devices are being communicated to, and selectively address the peripheral devices.

  • Patent number: 6039258
    Abstract: A hand-held portable data collection system integrates ideal design features to improve and optimize the data collection process. The operator interface of the hand-held portable data collection system incorporates somatic feedback between the hand-held portable data terminal and the operator, thereby facilitating operation of the data terminal such as reading of optically readable indicia. The hand-held portable data collection system further provides optimal data collection by allowing for variable orientation of the reading field of view of the data file reader allowing for optimal positioning of the reader during the data collection process. Optically readable indicia may be disposed within the reading field of view of the data file reader without having to sight along the terminal as is typical with prior aim and shoot type data readers. The optically readable indicia may be readable regardless of orientational disposition.

  • Patent number: 6006100
    Abstract: Portable measuring devices which communicate by low power transceivers through a communication controller with a printer device collect weight and size data on articles to be shipped. The collected weight and size data are combined with origin and destination data, and labels are printed bearing pertinent shipping and routing information in machine readable format. The labels are attached to the articles to be shipped and accompany the articles to their respective destinations. At transfer points the labels are read by scanner devices which also communicate by low power transceiver links with the communication controller. The wireless linking of the scanner devices promotes human safety by the absence of cords which could cause entanglement of an operator in mechanized conveying equipment. The communication controllers at each stage of the shipping process have the capability of transferring received and updated status information on the shipped articles to a central data station.

  • Patent number: 5978569
    Abstract: 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.

  • Patent number: 5949776
    Abstract: A hierarchical communication system is described in which wireless local area networks (LANs) exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. In a premises LAN, a series of radio base stations and a backbone LAN make up an infrastructure network. The infrastructure network and at least one mobile computing device make up a higher-power LAN, utilizing a frequency hopping protocol. A lower-power LAN allows for radio communication between a mobile computing device and peripheral devices, utilizing a single-frequency spread spectrum protocol. A vehicular LAN provides for short-range communication between a vehicle terminal and a portable terminal. When out of direct RF range of the premises LAN, the vehicle terminal maintains indirect communication when necessary with the premises LAN via one of several alternate RF channels.

  • Patent number: 5943421
    Abstract: A data processing system (100) includes a data processor or CPU (102) having decompression circuitry (208, 212) and decryption circuitry (210, 214) that operates on compressed/encrypted data to produce decompressed and decrypted data. The data processing system includes memory (104) in which instructions and data are stored in a compressed (110) and/or encrypted (114) format. The CPU (102) retrieves the compressed/encrypted data over a system bus (106). A bus interface unit (200) within the CPU (102) receives the compressed/encrypted data, decompresses and decrypts the data and stores the data in cache memory (202). An execution unit (204) and other components within the CPU (102) retrieve the decompressed and decrypted data and operate upon it. Alternatively, upon retrieval of compressed/encrypted data from memory (104) the data is stored in cache memory (202) in its compressed/encrypted format.

  • Patent number: 5940771
    Abstract: A data collection network supports roaming terminals which may enter and exit a sleep mode to conserve power. A plurality of base stations each periodically transmit pending message indications to those roaming data collection terminals in range. Instead of requiring the transceiver within each terminal to always be active, the receiver is activated in synchrony with the transmissions of pending message indications from at least one of the base stations. Otherwise, the terminal may deactivate the transceiver, i.e., place it in a sleep state. The terminal may also sleep through pluralities of transmissions of pending message indications, and, thereafter, awake in synchrony to receive subsequent pending message indications. To minimize noise, the terminal may operate using a lower frequency system clock when not collecting data. When collecting data, especially where processing time proves more critical, the system clock frequency is increased.

  • Patent number: 5928292
    Abstract: A vehicle for transport, fork lift or delivery route operations, for example, includes on-board peripherals which are coupled through a Local Area Network (LAN) into a data system. A LAN data bus provides selective access to the peripherals or data devices such as, for example, a large area display, a keyboard, a printer and a data terminal. The data system controls or provides data on tasks executed by or in connection with the operation of the vehicle. To increase the versatility of the vehicle, the data terminal, multiple data terminals, or any of the other data devices may be removably coupled to the LAN to be operable externally of the vehicle. A mobile mount adapter provides a secure electrical connection of a respective data terminal to the LAN to removably incorporate the data terminal into the data system, and provide a common supply of both data and power to the data device.
