Abstract: Resonating sensors for use in high-pressure and high-temperature environments are provided. In one embodiment, an apparatus includes a sensor with a double-ended tuning fork piezoelectric resonator that includes a first tine and a second tine. These tines are spaced apart from one another so as to form a slot between the first and second tines. The width of the slot from the first tine to the second tine varies along the lengths of the first and second tines. Various other resonators, devices, systems, and methods are also disclosed.

Abstract: A button device includes a fixed support structure; a movable structure, laterally surrounded by the support structure and configured to deform at least in part under the action of an external force; and a fluid-tight protection cap. The movable structure includes a piston element, deformable elements having piezoelectric transducers arranged thereon, and anchor elements that couple the piston element to the deformable elements. When an external force acts on the piston element, the anchor elements transfer this force to the deformable elements and to the piezoelectric transducers, so as to sense the extent of this force.

Abstract: A piezoelectric sensor assembly for measuring a force quantity on a structure includes at least one piezoelectric sensor, each including an element and two electrodes each projecting outward from the element. An electronic processor of the assembly is configured to receive data from the sensor, wherein the data includes a voltage with a magnitude that is indicative of a dynamic load (i.e., amplitude modulation mode) placed upon the structure. The processor may be configured to interrogate the piezoelectric sensor for its resonant frequency change which is indicative of the load applied to the structure at low operation frequency and to which the piezoelectric sensor would not otherwise respond well. The dual mode operation of the piezoelectric sensor extends the frequency range of the strain measurement from the dynamic range to static or quasi-static range.

Abstract: A surgical scalpel handle with an internal chamber and a removable electromagnetic resonance signal generating cartridge and an electromagnetic resonance sensor system is disclosed. A surgical scalpel handle is provided for with an internal chamber comprised of two pieces, a front piece with a blade holder and a back piece and when attached, the front end section and the back end section together comprise an internal cavity. An electromagnetic resonance signal generating cartridge comprising one or more printed circuit boards (PCB) are in electrical contact upon which an application specific integrated circuit (ASIC) are mounted and having a magnet; a coil; and capacitor resonant circuit; an elastic member; a pressure sensitive feature; and having power source connections, and a removable power source having power source contacts; and power source connections complete the electrical contact between the electromagnetic signal generating cartridge and the removable power source housed in the internal cavity. An electromagnetic signal generating cartridge is disposed of in an internal cavity of a scalpel handle and generates an electromagnetic resonance signal. An electromagnetic sensor system apparatus with a sensor system disposed of vertical and horizontal planes is disclosed and is disposed of on a surgical table. The scalpel handle with an internal cavity and removable signal generating cartridge and with the electromagnetic sensor system apparatus with a sensor system can be used to digitally map the precise position, size, trajectory, shape, pressure and angle of the scalpel being used during surgical procedures. A pressure sensitive feature is disposed and in connection with the blade holder and the removable signal generating cartridge. The pressure exerted by a surgeon on the blade is transmitted through a blade holder to a pressure sensitive feature to switch from the stand by position of the cartridge to the on and generate an electromagnetic signal position. The emitted signals generated by the cartridge can be read by the provided for electromagnetic resonance sensor system to generate a digital record of coordinates in the x, y location in a horizontal plane and vertical plane as well as a digital record of trajectory of scalpel used during the procedure. The coordinates are stored in a memory device such as a RAM, tablet or computer. After communicating with a host machine, a monitor can display the surgeon's trace and exact location coordinates.
