Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.

An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly has a pair of opposing jaw members. One or more of the jaw members includes a support base, an electrical jaw lead, and a sealing plate coupled to the electrical jaw lead. The sealing plate has a stainless steel layer and one or more piezo electric sensors. The jaw member also includes an insulative plate disposed between the support base and the sealing plate.

An embodiment modular light-emitting diode (LED) display panel includes attachment points for use in attachment as part of a multi-panel modular LED display, a printed circuit board including a first side and an opposite second side, and a plastic casing attached to the opposite second side of the printed circuit board. A perimeter of the plastic casing is substantially rectangular and has a height and a width. The modular LED display panel further includes a display surface including a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board. The pixels are arranged in a rectangular array including at least fifty pixels. Each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch. The pitch is a predetermined constant number. The pitch does not depend on the height and the width.

A tactile sensor includes a pressure transducer encapsulated in an elastic material that defines a contact surface and provides a transmission path that transmits contact forces or pressure distributions applied to the contact surface to the pressure transducer. The pressure transducer can be enclosed in a protective housing that defines a chamber around the transducer. The housing can include one or more openings that expose the chamber to the exterior pressure. The tactile sensor can be made by applying the elastic material in liquid form and exposing the housing to a vacuum that removes air inside the chamber allowing the liquid elastic material to flow into the chamber. Once cured, the elastic material defines a contact surface of the tactile sensor and serves to transfer contact forces applied to the contact surface to the transducer.

Provided is a sensor module, a method for manufacturing a sensor module, and a blood pressure measurement device that can improve the holding force onto a soft portion. A sensor module 63 of a blood pressure measurement device 1 includes: a sensor base 72; a pressure sensor portion 71 fixed to the sensor base 72; a sensor head cover 73 including, on an outer surface, an opening 73a in a region that comes into contact with a wrist 100 and an inner surface 73g formed with unevenness, the sensor head cover 73 being fixed to the sensor base 72 and forming a gap portion 79 that communicates with the opening 73a between the inner surface 73g, the sensor base 72, and the pressure sensor portion 71; and a soft portion 74 disposed in the gap portion 79 and, at least, filling up the opening 73a and covering the pressure sensor portion 71.

Planar-magnetic transducers and headphone speakers are provided. The transducer includes a magnet, a diaphragm and an electrically conductive trace. The magnet is formed from a continuous piece of magnetic material. The magnet includes a first surface and a second surface opposite the first surface. The magnet includes at least one slot extending through the magnet from the first surface to the second surface. The diaphragm is mechanically coupled to a frame and disposed at a predetermined distance from the first surface of the magnet via the frame. The trace is coupled to the diaphragm. The trace is arranged in a predetermined pattern and at a predetermined position relative to the at least one slot of the magnet.

A device for measuring impedance of biological tissue may include electrodes and a voltage-to-current converter coupled to the electrodes to drive an alternating current (AC) through the tissue and sense an AC voltage. The converter may include an amplifier having first and second inputs and an output, a first voltage divider coupled to the first input, a second voltage divider coupled to the second input, a filter capacitor coupled between the output and the second voltage divider, a current limiting resistor coupled between the second input the second voltage divider, and a bypass capacitor coupled to the second input of the amplifier and in parallel with the resistor. A single-ended amplitude modulation (AM) demodulator may demodulate the AC voltage and generate a corresponding baseband voltage representing the impedance. The device may also include an output circuit to generate output signals representative of DC and AC components of the baseband voltage.
