A patient transport apparatus with a base, a litter comprising a support surface, and a lift mechanism to facilitate arranging the litter at different heights relative to the base between a plurality of lift configurations including a fully-retracted configuration and a fully-extended configuration. The lift mechanism includes an actuator including a cylinder, fluid reservoir, and a pump driven by a motor to direct hydraulic fluid from the fluid reservoir to the cylinder. A sensor outputs a signal indicative of a magnitude of pressure in the cylinder. A user interface with an input control is provided. A controller determines a target parameter for the motor and, in response to user engagement with the input control, drives the motor at the target parameter to effect movement of the litter relative to the base at a predetermined rate irrespective of a weight of a patient supported on the litter.

The invention discloses a system for controlling the movement of a personal mobility vehicle including a processing unit that receives and processes a location data of one or more obstacles over a period of time, determines a change frequency of change of location of the obstacles during the period of time, and generates a movement state categorization of the obstacles categorizing them into either a dynamic obstacle or a static obstacle. The processing unit further determines a dynamic distance traveled by the dynamic obstacle during the period of time, the velocity of the dynamic obstacle, determines movement probability data that relates to the probability of movement of a static obstacle based on the change frequency of change of location, and, determines velocity prediction data of a dynamic obstacle based on the velocity of dynamic obstacles during various time intervals of the time period.

A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface. Adjustments to inflation or deflation of one or more bladders are made to achieve a desired immersion amount within a tolerance range between upper and lower TOF thresholds.

A method and system for patient monitoring, the system comprising a surveillance camera configured to generate a plurality of frames showing an area in which a patient in a bed is being monitored, and a computer system comprising memory and logic circuitry configured to determine bed rails positions of the bed, identify a position of the patient, and generate signals that control the bed rails of a bed based on the bed rails positions and the position of the patient.

Provided is a robot including a main body having a traveling wheel and a traveling motor for rotating the traveling wheel, a seating body disposed above the main body, a left projector disposed at a left side of the main body to scan a beam toward a left lower direction, a right projector disposed at a right side of the main body to scan a beam toward a right lower direction, and a processor for controlling the traveling motor, the left projector, and the right projector.

A power transfer system comprises a patient transport apparatus and a power transfer device. The power transfer system provides convenience and ease of connection between a power source and the patient transport apparatus to provide power to one or more electrically powered devices on the patient transport apparatus or to provide energy for an energy storage device on the patient transport apparatus.

A patient transport apparatus comprising a support frame, a base, a bracket coupled to the support frame and comprising a channel being non-linear, a frame assembly coupled between the support frame and the base and comprising a slidable member disposed in the channel, the slidable member being moveable between a plurality of different positions in the channel to place the support frame in a plurality of different poses relative to the base. The patient transport apparatus also comprises a sensor configured to detect the slidable member in the channel and produce a reading, as well as a controller coupled to the sensor and configured to receive the reading from the sensor, determine the position of the slidable member in the channel based on the reading, and determine the pose of the support frame relative to the base based on the determined position of the slidable member.

The movement module executes the control parameters to move around and includes one or more sensors to detect the information. The holder includes one or more sensors to sense the information.

A support cushion to ameliorate the incidence of pressure ulcers, the support cushion comprising: an open or closed cell support structure; at least one cavity formed within the support structure; at least one vibrational device located within at least one of the cavities and imparting vibration to the support structure; a controller controlling operation of the vibrational device to adjust one or more of intensity, duration and location of vibrations in a predetermined manner according to one of a number of selected programmes, and at least one sensor adapted to map a pressure (weight) distribution map of a user. The support cushion may be adjustable in vibration intensity, duration, and location depending on the mapped pressure distribution. The mapped pressure distribution and history of vibrational intensity, duration, and location may also be logged for diagnosis and treatment purposes.

An auxiliary loading device of a stretcher including a winch having a support frame rotatably supporting a spool, a tow strap wound on the spool and having a tow hook attachable to the stretcher, and a motor connected and configured to rotate the spool in a first direction for winding the tow strap on the spool and in a second direction for unwinding the tow strap from the spool. A sensor is connected to the winch to detect a value of a parameter indicative of a tension of a unwound section of the tow strap including the tow hook, and an electronic control unit operatively connected to the sensor unit and the motor of the winch to stop rotation of the spool when operated to rotate in the second direction if the value of the parameter indicative of the tension is less than or equal to a reference value.
