A detection system includes an acquisition unit, a calculation unit, a determination unit and a correction unit. The acquisition unit acquires measurement information from a load distribution sensor that detects a distribution of a load received from a sole of a subject. The calculation unit calculates a total load value of a sole region corresponding to the position of a sole of one leg of the subject, based on the measurement information. The determination unit determines an action state of the one leg based on the total load value. The correction unit starts to offset the total load value using an offset filter that decreases an offset amount with time elapse, in response to a determination that the action state is a first action state where the total load value tends to increase and is equal to or larger than a preset determination value.

A device for measuring hair properties has a first part (I) and a second part (II) between which hair (H) is guided. The first part includes a measuring probe (MP), and the second part is arranged for deforming the hair against the measuring probe. While the device moves along the hair, the measuring probe experiences both a friction force resulting from the hair being guided along the measuring probe, and a deformation force resulting from hair deformation by the second part against the measuring probe. The second part includes a pressure element (PB, S) for pressing the hair against the measuring probe. In alternative embodiments, the second part comprises alignment elements (AE) at opposite sides of the measuring probe, and guidance elements (G) for mitigating an influence of an angle at which the device is applied to the hair to the friction force and/or the deformation force.

Sleep tracking systems and techniques for monitoring two or more co-sleepers in a single bed are disclosed. Such systems and techniques may incorporate sleeper identification, as well as various non-user-specific aspects. Some implementations may incorporate user-specific or user-tailored alarm functionality.

A patient transport apparatus transports a patient over a surface. The patient transport apparatus comprises a support structure comprising a base, a patient support surface, and a reference sensor arranged to sense inclination of the support structure. A drive system is coupled to the support structure and operable to propel the patient transport apparatus. A handle assembly is operable by a user to control operation of the drive system. The handle assembly comprises a handle movable relative to the base and a position sensor arranged to sense positioning of the handle. A controller is coupled to the reference sensor and the position sensor, and is adapted to control the drive system in response to signals received from the reference sensor and the position sensor.

Blood pressure detection apparatuses and methods for detecting a blood pressure of a user are described comprising optical sensors/detectors and a force sensor and, in some embodiments, comprising only a force sensor, measuring force applied by a finger. Blood pressure is measured by applying an increasing (or decreasing) force or pressure with a finger of the user on at least the force sensor, which, in some embodiments, may be a plurality of increasing pressure steps, each step being held within a predetermined acceptable pressure/force tolerance range for a predetermined hold time, and measuring the force applied by the finger and, in some embodiments, optically measuring the blood in a vessel in the finger relating to the applied pressure/force. Feedback (visual, haptic, sound) of the applied pressure is provided to the user.

The invention provides a system for characterizing a patient including a substrate, a first electrode, a second electrode, and an electrical system. The electrical system is connected to the substrate and worn entirely on the patient's body. The electrical system in electrical contact with both the first and second electrodes and configured to inject an alternating electrical current through the first electrode and into the region of tissue. The electrical system is configured to measure a first electrical signal from the region of tissue through the second electrode. The electrical system is configured to measure a second electrical signal from the region of tissue.

Disclosed herein is a gait analysis apparatus that is configured to provide multidimensional measures of the gait of an individual as the individual traverses the gait analysis apparatus. The gait analysis apparatus may be configured to provide a gait measuring processing device with the multidimensional measurements. Based on the multidimensional measurements, the gait measuring process device may, for example, diagnose the test subject with lameness or particular neuromuscular dysfunctions (NM) disease and/or injury, monitor progression of lameness or a particular NM disease and/or injury over time, determine a static weight as the test subject is traversing, monitor the static weight of the test subject over an extended period time, and/or determine which measurements may be used as biomarkers to identify lameness or the particular NM disease and/or injury. A system including a gait analysis apparatus is also disclosed.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a cup and ball joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.
