A modular wristband and sensor system and method of using the same are disclosed. The system uses top and bottom sensor modules that contain conductive ports for connection to wristbands' conductive ports. The wristbands' conductive ports are electrically connected to wires embedded within each wristband segment. These allow for the transfer of data and power between the bands and the top and bottom sensor modules. Having power and data conducted through wristbands into sensors makes it possible for wristband sensors to have swappable bands while maintaining connectivity. Other embodiments include a wristband that includes swappable top and bottom sensor modules communicating wirelessly with each other.

In one aspect, a sample collection device for collecting a biological sample is disclosed, which comprises a sample-receiving cup having a body that extends from a proximal opening to a distal opening, where the proximal opening is configured for receiving a biological sample. The sample collection device further includes a sensor comprising at least one sensing unit, where the sensor is sealingly connected to the distal opening of the sample-receiving cup such that the sensing unit is exposed to the distal opening. A reservoir for storing one or more sample-processing reagents is provided in the fluid-receiving cup such that the sensing unit is in fluid contact with the reagent(s) stored in the reservoir. A frangible membrane separates the reservoir from the proximal opening.

A ring-shaped earphone may be configured to be worn in an ear. When not worn in the ear, the ring-shaped earphone may be conveniently stored on a finger. In one example, the ring-shaped earphone may include a ring-shaped body defined by an outer cylindrical surface and an inner cylindrical surface. The earphone may include a speaker within the ring-shaped body. The speaker may be configured to project sound through a speaker opening in the outer cylindrical surface. The earphone may include a microphone within the housing. The microphone may be configured to receive sound through a microphone opening in the inner cylindrical surface.

The invention provides a magnetic inductive sensing device (30) comprising a loop antenna (10) for inductively coupling with electromagnetic (EM) signals emitted from a medium in response to stimulation of the medium with electromagnetic excitation signals. The device includes an electromagnetic shield (36) element which is arranged such as to intercept electromagnetic signals travelling to or from the antenna. The shield element is formed of conductive material such as to block electrical field components of incident signals but further incorporates a non-conductive gap in the material so as to prevent the formation of eddy currents. A loop of the antenna is broken by an opening, the opening being bridged by a capacitor, and the device comprises a signal processing means which is electrically coupled to the antenna via only a single point of the antenna, located to one side of the opening.

A sensor includes: a needle member defining a hollow portion, wherein the needle member comprises a peripheral wall, and a through hole extends through the peripheral wall; an elongated detection member positioned in the hollow portion and extending along a longitudinal direction of the needle member; and at least one protruding portion that protrudes radially inward from the peripheral wall and restricts movement of the detection member in a radial direction.

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.

A surgical robotic system includes a plurality of magneto sensors for measuring a torque, axial force, angle, position, or speed of various driven members in the surgical robotic system.

The present invention provides an apparatus for protecting dental patient hearing through noise reduction, the apparatus comprising: a main body portion provided in a form that can be mounted on both ears of a user; a microphone module that is provided on one side of the main body portion and collects external sound signals generated from the outside; a noise filter module that is built in the main body portion and filters the external sound signals to block or reduces noise signals included in the external sound signals; and a speaker module that is built in the main body portion and provided on the other side of the main body portion corresponding to the ears of the user, and that outputs sound signals filtered by the noise filter module.

Various embodiments of a die carrier package and a method of forming such package are disclosed. The package includes one or more dies disposed within a cavity of a carrier substrate, where a first die contact of one or more of the dies is electrically connected to a first die pad disposed on a recessed surface of the cavity, and a second die contact of one or more of the dies is electrically connected to a second die pad also disposed on the recessed surface. The first and second die pads are electrically connected to first and second package contacts respectively. The first and second package contacts are disposed on a first major surface of the carrier substrate adjacent the cavity.

An electronic face-identification device, which performs face scanning with ultrasonic waves, includes a housing and an ultrasound device disposed within the housing. The ultrasound device may be configured to transmit ultrasonic waves through air to a face and scan the face with the ultrasonic waves, to receive reflected waves through the air corresponding to reflections of the ultrasonic waves from the face, and to perform a recognition process for the face based on reflections of the ultrasonic waves from the face. The ultrasound device may include a plurality of ultrasound transducers, and electronic circuitry configured to transmit signals to the ultrasound transducers and receive signals from the ultrasound transducers. The face-identification device may be incorporated into various electronic equipment, such as hand-held equipment in the form of smartphones and tablet computers, as well as in larger scale installations at airports, workplace entryways, and the like.
