Various embodiments herein comprise a handheld load sensing device. In one embodiment, the device comprises a force sensor (e.g., a mechanical spring or an electromechanical load cell) adapted to receive a force, an input/output interface, and an adjustable attachment mechanism adapted to reversibly attach a surgical device. In another embodiment, the force sensor detects the amount of force applied during the deployment of the surgical device in a patient and outputs a force value representative thereof via the input/output interface. Also provided herein are methods of making and using load sensing devices.
Abstract:
An apparatus and method utilizes photonics, particularly lasers, and biometric feedback for physiological and neurological stimulation. While many areas of the body are candidates, such laser stimulation is particularly directed to the outer ear. Lasers positioned over the ear stimulate targets on the outer ear for pain and stress management and regulation of the autonomic nervous system to affect symptoms and clinical conditions. Laser positioning, wavelength, aiming, focus, power, power density, timing, and sequencing are managed and modified dynamically in real time to effect a personalized and effective treatment protocol.
Abstract:
Micro-electromagnetically actuated latched miniature relay switches formed from laminate layers comprising a spring and magnet, electromagnetic coils, magnetic latching material, and transmission line with contacts. Preferably the miniature relay switches transmit up to about 50 W of DC or AC line power, and carry up to about 10 A of load current, with an overall volume of less than about 100 mm3. In addition to switching large power, the device preferably requires less than 3 V to actuate, and has a latching feature that retains the switch state after actuation without the need for external applied voltage or current.

Abstract:
Systems and methods are provided for patterning biological and non-biological material at specific sites on a plate, as well as growing three dimensional structures. Preferred embodiments comprise a plate with regions that will trap gas, usually in the form of bubbles, when the plate is submerged in liquid. Other embodiment of the present invention include a method for placing materials on the plate at pre-determined locations through the use of trapped gas to prevent materials from collecting at unwanted regions. The plate has great utility for plating cells and tissues at specific sites, such as on an array. The disclosed method can also be used to coat the surface of a plate with coatings at specific locations for patterned coating applications and to build up materials to produce three dimensional structures, including micromechanical structures—where the structures may be formed from living or non-living material, tissue or non-tissue, organic or inorganic, and the like.
Abstract:
A miniature wireless pressure sensor has an inductor and a capacitor. The inductor and the capacitor form a L-C resonator with a resonate frequency. The inductor's inductance is affected by a slidable electro-magnetic element. When an outside pressure is applied onto the element, it causes the element to move and such movement changes the inductance of the inductor. Because of that, the resonate frequency is changed. Therefore, the change in resonate frequency indicates a change in the outside pressure. The L-C resonator is calibrated to correlate with the outside pressure. Such a miniature wireless pressure sensor facilitates the monitoring of physiological pressure in different part of human body such as eyes and cranium.
