Abstract: A method for monitoring operation of an archery bow includes attaching an apparatus to a bow cord. The apparatus includes a processor, a monitoring device electrically coupled with the processor, a wireless communication module electrically coupled with the processor, and a power supply electrically coupled with each of the processor and the wireless communication module. The method further includes detecting, by the monitoring device, a tension of the bow cord. The method also includes generating, by the processor and based upon the detected tension of the bow cord, data concerning tension of the bow cord. The method further includes wirelessly transmitting, by the wireless communication module, the data to a remote computing device. The method also includes receiving, by the remote computing device, the data. The method also includes presenting, by the remote computing device and based upon the data, information to a user reflecting the detected tension.

Abstract: A composite wafer level MEMS force dies including a spacer coupled to a sensor is described herein. The sensor includes at least one flexible sensing element, such as a beam or diaphragm, which have one or more sensor elements formed thereon. Bonding pads connected to the sensor elements are placed on the outer periphery of the sensor. The spacer, which protects the flexible sensing element and the wire bonding pads, is bonded to the sensor. For the beam version, the bond is implemented at the outer edges of the die. For the diaphragm version, the bond is implemented in the center of the die. An interior gap between the spacer and the sensor allows the flexible sensing element to deflect. The gap can also be used to limit the amount of deflection of the flexible sensing element in order to provide overload protection.

Abstract: A load suspension and weighing system for a removable reservoir unit of a portable dialysis machine includes a centrally located flexure assembly. The flexure assembly includes magnets and a number of flexure rings which allow for movement of the magnets about a fixed circuit board. Sensors in the circuit board sense changes in the magnetic field as the magnets move in relation to the circuit board. The magnetic field changes produce a voltage output which is used by a processor to generate weight calculations. The top of the flexure assembly is attached to the interior of the dialysis machine. The entirety of the reservoir unit is suspended by a first internal frame that is attached to the bottom of the flexure assembly. Having a single flexure assembly positioned above the reservoir unit provides more accurate weight measurements while also preventing damage to the assembly from water spillage.

Abstract: A detection circuit for detecting changes in capacitance. The detection circuit includes a tuned ratio circuit and an alternating current (AC) source AC-coupled to the tuned ratio circuit. The tuned ratio circuit includes first and second tuned circuits that are tuned to, or close, to the frequency of the AC source. Output circuitry is coupled between the two tuned circuits. During use as a transducer, an active capacitive transducer is inductively coupled to the first tuned circuit. Changes in the capacitance of the active capacitive transducer cause changes in the tuning of the first tuned circuit. The output circuitry generates an output signal that is a function of the difference between the tunings of the first and second tuned circuits.

Abstract: A flow velocity detector for detecting a flow velocity of a fluid flowing through a flow passage is provided, the flow velocity detector including a flow passage-forming section which defines the flow passage; a stress light-emitting section which is arranged at the flow passage-forming section to receive a stress having a magnitude depending on the flow velocity of the fluid and which emits a light of which amount corresponds to a change of the received stress; and a light-receiving sensor which receives the light emitted by the stress light-emitting section. The flow velocity of the fluid is detected based on an amount of the light received by the light-receiving sensor to generate a detection signal. Accordingly, the structure is simple and small-sized, and the flow velocity of the fluid can be detected at low cost.

Abstract: The invention is a microfabricated silicon cantilever with a stiffness appropriate to resolve forces of interest in working with micro objects. Stiffnesses may range from about 10 piconewtons per micron of deflection, to about 1 millinewton per micron of deflection. There is a set of micro weights of appropriate masses that is used to calibrate the force gages. The weights are captive to a ring on a handle so that they are free to move, but will not get lost.
