An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.

Devices and methods are described for providing continuous measurement of an analyte concentration. In some embodiments, the device has a sensing mechanism and a sensing membrane that includes at least one surface-active group-containing polymer and that is located over the sensing mechanism. The sensing membrane may have a bioprotective layer configured to substantially block the effect and/or influence of non-constant noise-causing species.

A method for diagnosing a joint condition includes in one embodiment: creating a 3d model of the patient specific bone; registering the patient's bone with the bone model; tracking the motion of the patient specific bone through a range of motion; selecting a database including empirical mathematical descriptions of the motion of a plurality actual bones through ranges of motion; and comparing the motion of the patient specific bone to the database.

An apparatus and method for determining tissue oxygenation such as arterial and venous oxygenation and cerebral oxygenation. In one embodiment the optical properties of tissue are determined using measured light attenuations at a set of wavelengths. By choosing distinct wavelengths and using light attenuation information, the influence of variables such as light scattering, absorption and other optical tissue properties can be minimized.

A medical monitor includes a lanyard and an electronic package supported in the manner of a pendant. The lanyard includes integral electrodes or other sensors for making physiological measurements, auxiliary components and connectors for electrically connecting the electrodes or sensors to the electronic package. The physiological measurements may be stored in the monitor for later readout, or may be transmitted, before or after processing, to a remote location.

A closed loop brain-machine interface is disclosed. The closed loop brain-machine interface translates one or more neural signals into a movement, or a series of movements, performed by a machine. The close-loop brain-machine interface also provides sensory feedback to the subject. Methods of employing the closed loop brain-machine interface are also disclosed.

The invention is a medical monitor including an electronic circuit configured to receive a signal from the physiological sensor. A microcomputer configured to process the signal from the physiological sensor generates a value representative of the physiological parameter. The microcomputer is also configured to cause the medical monitor to display an in-service help screen on a display on the medical monitor in response to a detection of a predetermined number of out of range values of the physiological parameter. The microcomputer can also be configured to process a second signal from a second sensor representative of a second parameter and the microcomputer configured to cause the medical monitor to display an in-service help screen on a display on the medical monitor in response to a detection of a predetermined number of out of range values of the second parameter.

Provided are embodiments of systems, computer medium and computer-implemented methods for monitoring the health of an employee. A method for monitoring the health of an employee including collecting health data corresponding to at least one of biometric health data and biomechanical health data for an employee acquired via a plurality of health sensors located throughout the employee's workstation, determining a health profile for the employee based at least in part on the collected health data, and serving, to an employee computer for display, health profile content comprising an avatar configured to communicate information relating to the health profile for the employee. The plurality of health sensors including at least one of biometric sensors and biomechanical sensors.

Disclosed herein are methods of treating a patient, comprising providing a compressible attenuation device that is moveable from a first, introduction configuration to a second, implanted configuration. The attenuation device is introduced into a treatment site. In one embodiment, the treatment site is the bladder. In another embodiment, the treatment site is the abdominal cavity. The volume of the attenuation devices changes in response to pressure changes in the treatment site and attenuates pressure changes in the bladder.

An ultrasonic probe includes a light irradiating portion configured to radiate light for generating ultrasonic waves from a light absorber, an ultrasonic transducing portion configured to transduce the ultrasonic waves to an electric signal, and a light guide member configured to introduce light from a light source to the light irradiating portion. A light irradiating region of the light irradiating portion is included within an ultrasonic receiving region of the ultrasonic transducing portion.

A collar for pet animals may have sensor elements remotely actuatable to measure vital signs of the animal (such as respiration, pulse, temperature and movement) and a processor that can interpret the results of multiple vital sign readings. A two way communication device alerts the pet owner, veterinarian or authorities. A veterinarian can remotely take a particular vital sign measurement when alerted. The sensor elements embedded in the collar's band has at least one elastic pin extending toward the animal's neck to gather data processed on the collar or remotely. To improve STN ratio, an elastic layer may absorb noise from friction due to movement of the animal's head. The collar may adjust the tightness of the band for taking vital sign readings. For example pump may injects air through a tubular compertment running along the circumference of the band. A safety mechanism may release the collar.
