摘要:
An adjustable write-equalized recording circuit for recording data onto a magnetic tape. The circuit variably adjusts the amplitude of write-equalization pulses relative to the data waveform by an amount that can be either preset or determined during operation.
摘要:
Sheet dispensers, which provide feedback to a user or provide a unique function to a user, are disclosed. Visual, audio, aromatic, or other types of feedback may be provided to a user by the sheet dispenser. Sheet dispensers suitable for use as a switch, a room deodorizer, a flame-generating device, or a combination thereof are disclosed. A method of activating a switch-controlled object is also disclosed. Further, a method of making sheet dispensers is also disclosed.
摘要:
Method and system are disclosed for determining conditions of components that are removably coupled to articles of personal protection equipment (PPE) by tracking the components against predetermined criteria.
摘要:
An electronic marker and method of making an electronic marker for marking obscured articles. The marker includes a core made of flexible, and sometimes high permeability magnetic material and a solenoid disposed around the core. A capacitor is electrically coupled with the solenoid, and the marker is tuned to respond to a signal at a characteristic resonant frequency. The marker can attached to a conduit to be buried underground. The marker can further include a radio frequency identification chip.
摘要:
Methods of monitoring items and/or materials from a manufacturing process. One embodiment of the invention provides a method of monitoring items and/or materials from a manufacturing process using a plurality of RFID tagged containers, and a plurality of stations associated with different portions of the manufacturing process, where each station includes an RFID reader.
摘要:
An activity sensor which provides an indication of motion caused by changes in acceleration of a person or animal, and wherein such changes of motion are sensed by a movable magnet which is biased to a rest position along a guide. The axis of the path of movement of the movable magnet is substantially parallel to the direction of accelerations of interest. A Hall effect sensor is provided for sensing motions of the movable magnet from its rest position, and it provides an output proportional to these movements.
摘要:
A method for tracking procedures performed on personal protection equipment (PPE) and actions of individuals includes the following steps. An article of PPE configured with a smart tag is provided to an individual prior to performance of a task. After the individual performs the task, the article of PPE is processed. Information is retrieved from the smart tag during at least one of: before, during and after processing the article of PPE. After the performance of the task, the individual's data is read and the individual enters into a designated area.
摘要:
Non-networked radio frequency identification (RFID) systems and methods are described that use RFID tags to exchange information between non-networked RFID readers. The RFID tags may store information about conditions the RFID-tagged items have encountered while being processed. RFID readers may dynamically update the information stored on the RFID tags as the RFID-tagged items are processed at nodes. An RFID tag may include a processor that dynamically determines process control instructions based on the information.
摘要:
An article, system and method related to a magnetomechanical marker used to mark stationary assets. Magnetomechanical markers can be arranged in clusters and associated with stationary assets, including assets buried underground. Markers can be associated with an asset by being attached to the asset, arranged in a particular spatial relationship with the asset, or in any other appropriate way. A portable locating device can be used to generate an alternating magnetic field to activate the magnetomechanical marker and thus locate the asset.
