Abstract: An RFID tag (200) and similar control/sensing unit (300) for a communications system are described. The control/sensing unit has a control element (301) having one or more states, and include an antenna (207) as well as an electrical circuit (201-206) generating a pulse control signal for controlling transmission from the antenna and varying a parameter of the pulse control signal in dependence on the state of the control element (301). Also disclosed is a receiving communication unit in the form of a base unit or system controller for such a communications system, the unit including a receiver (100) for receiving a pulsed RF signal and an electrical circuit (105-106) for detecting a parameter of the pulsed RF signal. An output circuit (107) then produces an output control signal dependent on the detected parameter of the pulsed RF signal.

Abstract: An RFID transceiver tag is proposed for use in a monitoring system for detecting a change in position of the tag relative to an associated RFID tag or to the environment surrounding or between the tags. The transceiver tag has a detector for detecting a characteristic of a signal transmitted between the transceiver tag and the associated RFID tag and for creating a trigger signal if the detector detects that the characteristic has changed beyond a predetermined extent; and a transmitter for transmitting a signal to a remote controller on receipt of the trigger signal from the detector.

Abstract: The present invention relates to a refillable tape cassette for accomodating a supply of printable tape. In order to avoid the need for different tape cassettes for different tape widths the tape cassette is capable of selectively housing supplies of tapes of different widths. Alternatively or additionally, the tape cassette can have a housing comprising a base on which the tape supply can be releasably fixed, and a lid fixed to the base, wherein the lid is pivotally mounted to the base by means of a hinge, Further, according to the invention, the windings of refill tape units are held together by means of a strip of adhesive or by means of wax on the axial ends of the units, or by scuffing the backing layer of an image receiving tape which is broader than the image receiving layer.

Abstract: A tape printing apparatus having a thermal print head for printing an image on an image receiving tape, the print head having a first mode of operation for printing on an image receiving tape with an ink ribbon, and a second mode of operation for printing on thermally sensitive image receiving tape. A detector detects whether ink ribbon is present or absent in a receiving mechanism and provides a signal to a control mechanism indicative of the presence or absence of ink ribbon, the control mechanism being arranged to control the print head to have the first mode of operation when ink ribbon is present and the second mode of operation when no ink ribbon is present.

Abstract: A portable printer which can print on a variety of surfaces is disclosed. The printer has a number of failsafe features which improve its operation and the quality of print. In particular, printing is inhibited in a certain number of situations. Alternatively or additionally, a maintenance sequence can be implemented when the printing unit is removed from a base location. A set of absorbent strips additionally or alternatively allow for the ink jet nozzles to be discharged within the print area.

Abstract: The invention relates to a tape printing apparatus for printing an image on an image receiving tape. In order to detect characteristics of the tape thus avoiding representation means on a tape cassette, it is proposed to have detecting means for detecting-markings provided on the image receiving tape, which provide information on a characteristic of the tape; and the tape printing apparatus is controlled in accordance with the detected characteristics. Alternatively, it is proposed to have monitoring means for monitoring the speed of the image receiving tape, which detect marking on the image receiving tape whereby the printing means is controlled in dependence on the detected speed. Consequently, the exact tape speed is considered for printing purposes, even when slippage between driving means and tape occurs.

Abstract: A portable printer is provided which provides active cooperation between a computer and the portable printer unit. A number of different features are introduced into the printing unit which allow greater responsiveness from the computer responsive to actions taken at the printer unit.

Abstract: The invention relates to a tape holding case housing a supply of image receiving tape and includes an angled surface to bend the surface of the tape approximately 90°, the angled surface being provided upstream of the printing position of the tape. The tape holding case also includes a casing that is designed to attach the tape holding case to an identically shaped tape holding case.

Abstract: The invention refers to a tape printing apparatus (2) used with tape cassettes (20, 220, 243, 260, 443). In order to make insertion and removal easier, the tape cassette is provided with a surface controlling the position of a printhead (22, 222, 322, 422) and/or a platen. When the cassette is inserted, printhead and platen are automatically separated such that the tape (24) can be introduced between them, and afterwards moved in the operative position. Further, an over center mechanism is proposed for moving printhead and platen. The tape cassette (443) can provide a 90.degree. bend in the tape (24) upstream the printing position, and the motor (42) can be located besides the zone for accommodating the image receiving tape (24). The cassette can be made attachable to other cassettes, and the means for attaching can guide and hold the cassette in the tape printer.

Abstract: A tape printing apparatus arranged to be used with a tape holding case. The case holds a first supply of image receiving tape and a second supply of laminating tape.
