Thickwire: Half inch diameter coax cable.

Thinwire: Thin coaxial cable similar to that used for television/video hookups.

Throughput: (1) The amount of merchandise shipped through a system or warehouse in a given time. This is referred to in cases, lines, or tons of product. (2) The rate of movement of material through a system.

Time Study: A work measurement technique consisting of careful time measurement of the task with a time measuring instrument, adjusted for any observed variance from normal effort or pace to allow adequate time for such items as foreign elements, unavoidable or machine delays, rest to overcome fatigue, and personal needs. Learning or progress effects may also be considered. If the task is of sufficient length, it is normally broken down into short, relatively homogeneous work elements, each of which is treated separately as well as in combination with the rest.

Token: The character sequence or frame, passed in sequence from node to node, to indicate that the node controlling ir has the right to transmit for a given amount of time.

Token Ring: Developed by IBM, this 4 or 16 Mbps network uses a ring topology and a token-passing access method.

Topology: The arrangement of the nodes and connecting hardware that comprises the network. Types include the ring, bus, star and tree.

Tote Box: A small durable container usually used for order picking and/or shipping of small items.

Transceiver: The actual device that interfaces between the network and the local node. The term generally refers to to any connector such as a MAU, that actively converts signals between the network and the local node.

Transfer Mechanism: Any mechanism that transfers objects onto or off of a conveyor line or from one conveyor line to another.

Travel Expenses: Out-of-pocket expenses for work done at a customer location such as meals, lodging, and transportation.

Turret Truck: A class of material handling vehicles in which the forks are attached to a device permitting their rotation to service either side of the storage aisle. Turret trucks can swing their forks through 180 degrees and can load pallets from either side of the machine. These units vary in their aisle requirements and in their flexibility but generally operate in aisle widths of 50 to 84 inches and with clearances only slightly larger than the size of the pallet itself.

Twisted Pair Cable: Inexpensive, multiple conductor cable comprised of one or more pairs of 18 to 24 gauge copper strands. The strands are twisted to improve protection against electromagnetic and radio frequency interference. The cable, which may be either shielded or unshielded, is used in low-speed communications, as telephone cable. It is used only in baseband networks because of its narrow bandwidth.

Two Way Container: A container whose configuration permits retrieving or discharging from opposite direction along the same horizontal axis.

UPS - Standby Type: (Uninterruptible Power Supply) During normal operation, the UPS routes raw utility AC power directly to the computer while trickle-charging the battery. When the incoming utility voltage drops below a certain value (typically 102VAC), a detection circuit actuates a transfer switch to connect to battery power via a DC-to-AC inverter. This switchover causes a momentary loss of power of typically 5-20msec.

UPS - Line-Interactive Type: With this UPS type, utility-generated power supplies the load under normal conditions. But the line-interactive system has boost/buck circuits that can add to (boost) or oppose (buck) the AC voltage from the power line. The boost/buck circuits offer voltage regulation, which can compensate for overvoltages or undervoltages in the AC input to the UPS.

UPS - On-Line Type: With an on-line UPS, AC power from the electric utility passes through an AC-to-DC converter to become direct current, which charges a storage battery. In addition to supplying DC to the battery, it also supplies the DC-to-AC inverter into which the computer load is plugged. Because the load is always powered by the DC-to-AC inverter, an on-line UPS has no switching time.

Unitization: Securing material to a pallet by strapping, wrapping, or other means to provide a secure load for handling by a fork truck.

Unix: A multitasking, multi-user computer operating system developed by AT&T.

UTP: Unshielded twisted pair, one or more cable pairs surrounded by insulation. UTP is commonly used a telephone wire.

Wand: A hand held scanning device used as a contact bar code reader. It is also referred to as a light pen. It is shaped like an oversize pen and an operator must guide it across the bar code.

Warehouse: A building for the storage of merchandise or commodities.

Wedge Reader: A device which transmits scanned bar code data to the CRT display just as if it had come from a keyboard.

Work Measurement: A generic term used to refer to the setting of a time standard by recognized industrial engineering technique, such as time study, standard data, work sampling, or predetermined motion time systems.

Work Sampling: An application of random sampling techniques to the study of work activities so that the proportions of time devoted to different elements of work can be estimated with a given degree of statistical validity.

Workstation: An established location in which something or someone stands or is assigned to stand or remain. This space includes that area necessary for the operation, material being processed or worked on, and the auxiliary equipment necessary to perform the assigned function.
