The invention provides a neck-worn sensor for simultaneously measuring a blood pressure (BP), pulse oximetry (SpO2), and other vital signs and hemodynamic parameters from a patient. The neck-worn sensor features a sensing portion having a flexible housing that is worn entirely on the patient's chest and encloses a battery, wireless transmitter, and all the sensor's sensing and electronic components. It measures electrocardiogram (ECG), impedance plethysmogram (IPG), photoplethysmogram (PPG), and phonocardiogram (PCG) waveforms, and collectively processes these to determine the vital signs and hemodynamic parameters. The sensor that measures PPG waveforms also includes a heating element to increase perfusion of tissue on the chest.

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,

A hearing aid module includes an elongated housing, an optical sensor module within the housing, an audio driver positioned within the housing adjacent the optical sensor module, and first and second light guides positioned near the audio driver. The module has a rectangular configuration with opposite first and second sides, opposite third and fourth sides, and opposite first and second ends. The first and second sides each include an opening. An ear tip is coupled to the housing first end and is configured to retain the module within the auditory canal. The first light guide guides light from an optical emitter through the opening in the housing first side and into skin of the auditory canal in a non-line of sight manner. The second light guide collects light from the skin of the auditory canal and directs the collected light to an optical detector in a non-line of sight manner.

A method to protect kidneys of a patient undergoing cardiac surgery patient including: administrating a diuretic to the patient to increase urine output of the patient during cardiac surgery, wherein the diuretic is administered during the cardiac surgery; anesthetizing the patient with a general anesthetic during the cardiac surgery; infusing an intravenous liquid into the patient during the cardiac surgery; monitoring a rate or amount of urine output of the patient during the cardiac surgery, and automatically adjusting a rate or amount of the intravenous liquid infused into the patient to achieve or exceed a target urine output during the cardiac surgery.

A surgical instrument includes a handle assembly, a power source coupled with the handle assembly, and a control circuit coupled with the handle assembly and the power source. The handle assembly, the power source, and the control circuit are configured to drive an end effector of a shaft assembly coupled with the handle assembly to perform an operation on tissue. The control circuit is configured to receive life deduction event data. The control circuit is configured to determine an end of life for the power source based on the life deduction event data.

A biological information measurement device operates using a battery as a power source, and enables the continuous measurement of biological information. The biological information measurement device is provided with: a battery charge level detection unit for detecting the charge level of the battery; a measurement control unit that ends measurement of biological information when the charge level of the battery falls below a threshold value during biological information measurement; and an information output unit that, when biological information measurement has been ended by the measurement control unit, outputs, to a display unit, information indicating the length of time over which biological information was measured.

The disclosure relates to a method for disassembling a marker array (10) comprising at least three optical markers (100) arranged according a determined array geometry configured to be tracked by a localization camera from an array fixation (11) to which the marker array (10) is connected, the method comprising, prior to or during disconnecting the marker array (10) from the array fixation (11), actuating a mechanism configured to selectively modify the array geometry so as to unable tracking of the marker array by the localization camera.

The present disclosure relates a multi-leaf collimator. The multi-leaf collimator may include a plurality of leaves. At least two leaves of the plurality of leaves may be movable parallel to each another. For each leaf of at least some of the plurality of leaves, at least one portion of the leaf may have thicknesses varying along a longitudinal direction of the each leaf. The each leaf may have a first end and a second end along the longitudinal direction of the each leaf.

An assembly and a method is described. The assembly includes a platform, a motive source, a sensor, a controller and a computerized system. The computerized system has logic configured to cause a processor to send a signal to the controller to cause the motive source to move the platform through at least a portion of a range of inclination angles and to receive data indicating at least one of muscle activity, movement, and ground reaction force applied to the platform at a determined angle, and to cause the processor to analyze the data to determine an orthotic angle for a user's foot.
