摘要： A force measuring apparatus uses a flexible cantilever beam engaging a tool at one end and a handle at the other end so that a force, normal to the beam, can be applied and delivered to the tool. Mounted in spaced apart longitudinal alignment on each side of the beam, is a tensioned wire, and a vibratory modulator in electromagnetic communication with the wire causing the wire to vibrate. A vibratory sensor is also positioned on each side of the beam in sensory communication with each respective wire. An electrical circuit is functionally enabled for receiving electrical signals from the vibratory sensor, the signals corresponding to a vibratory frequency of each of the wires, and for controlling the vibratory modulators to maintain the wires at resonant vibratory frequency, and for measuring a differential vibratory frequency between the wires, and finally, for calculating the magnitude of a force applied to the beam in such direction that one of the wires is incrementally further tensioned and the other of the wires is incrementally relaxed. The force magnitude is displayed on the apparatus.

摘要： A method of selectively waking up a plurality of RFID tags includes (a) providing a first RFID tag; (b) programming the first RFID tag to respond and wake up only to signals at a first sub-carrier frequency or with a first code; (c) providing a second RFID tag; and (d) programming the second RFID tag to respond and wake up only to signals at a second sub-carrier frequency or with a second code. A method of operating an RFID tag positioning system includes (a) positioning two real time location tracking active RFID readers in two respective locations; (b) positioning a first calibrating RFID tag at a fixed and known position; (c) moving a second calibrating RFID tag along a pre-determined path; (d) obtaining the first RFID reader's readings of location-related information of the RFID tags at a point in time; (e) obtaining the second RFID reader's readings of location-related information of the RFID tags at that point in time; and (f) comparing the readings with the known positions of the first and second calibrating tags.
