Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length.

An analyte detection device with intelligent identification function, includes: a transmitter; a sensor unit including a sensor base and a sensor with first parameter, and one end of the sensor inserted under the skin while the other end is installed in/on the sensor base; a bottom base; at least one physical unit with second parameter which corresponds to the first parameter arranged on the bottom base, on the sensor base or on/in the transmitter; and a detection circuit for detecting the second parameter which can be transmitted to the transmitter. Using this detection device, the transmitter can automatically identify the corresponding sensor information.

A handheld surgical instrument includes a motor that transmits rotational movement to a drill bit of the handheld surgical instrument. The drill bit extends through a depth measurement module with a depth measurement extension, and a cannula, which extends forward from the drill to measure bore depth. The depth measurement extension is moveably mounted to the drill so as to extend into the rotor bore of the motor. As the drill advances forward, the depth measurement extension remains static. As a result of the advancement of the drill, the rotor extends over the proximal end of the depth measurement extension. A controller is configured to determine a breakthrough time and a breakthrough displacement of the drill bit based on displacement data and derived signals. The controller is further configured to determine a proper length of a screw to be used in a fixation surgical procedure based on the displacement data.

Wearable apparatus for the treatment of mastitis, the apparatus comprising a mammary gland wearable comprising an array of light source elements thereon emitting electromagnetic radiation having a wavelength in the range of 380-1050 nm, a power supply coupled to the array of light source elements, the wearable configured to be worn against a mammary gland in use wherein the array of light source elements emit the radiation which penetrates epidermis of the mammary gland for the treatment of mastitis.

A gripping apparatus includes: a temperature adjusting device held in a substrate wherein the substrate defines an open region; a phase change material held within the open region and thermally coupled with the temperature adjusting device such that a temperature change in the temperature adjusting device causes a temperature change in the phase change material; and a controller connected to the temperature adjusting device and configured to send a signal to the temperature adjusting device to change its temperature and thereby change the temperature of the phase change material that is thermally coupled with the temperature adjusting device. The phase change material is either in a solid state and configured to grip a stick or in a liquid state and the phase change material and configured to loosen its grip on the stick such that the stick is capable of moving through the phase change material.

The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can be used in a variety of different applications, including as components of ingestible identifiers, such as may be found in ingestible event markers, e.g., pharma-informatics enabled pharmaceutical compositions.
