A syringe having an internal pressure gauge comprises a syringe barrel; a piston within the barrel; a spring coupled to the piston at a first position of the spring, the spring having a second portion that is movable in response to fluid pressure within a syringe cavity; and a pressure gauge having an indicator correlated to a plurality of positions of the second portion of the spring to indicate a pressure of a fluid. The spring can be a bellows. The fluid chamber can be in fluid communication with a cuff of an inflatable medical device, such as an endotracheal tube, such that the measured pressure comprises the fluid pressure within the cuff.

The spring can be a bellows. The first portion of the spring can be coupled to the piston to form a sliding seal with an inner wall of the syringe, and the second portion of the spring can move longitudinally within the syringe without sealing contact.

Devices, systems, and methods for autonomously folding a deformable laundry article are described. A folding device includes a rotatable platform configured to receive the article. A rotatable blade is suspended above the surface and a clamp rod is disposed parallel to a longitudinal axis of the blade. The clamp rod is configured to raise and lower from a surface of the rotatable platform, slidably move parallel to the surface, and clamp the deformable article to the surface in a lowered position. The blade is configured to raise and lower from the surface of the rotatable platform, slidably move parallel to the surface, slide under an unclamped portion of the article, lift the unclamped portion above the clamp rod, pass the unclamped portion over the clamp rod, and lower the free end to a resting position atop another portion of the article to fold the article.

Devices, systems, and methods for repositioning a deformable laundry article are described. For example, a robotic device includes a conveyor configured to transfer the deformable laundry article outside of a work volume, two or more lifters including grippers individually anchored about the perimeter of the work volume, two or more sensors disposed at fixed locations about the work volume, and a memory storing data indicative of repositioned deformable laundry articles. A controller is in operative communication with the memory, the two or more sensors, and the two or more lifters. The controller is configured to receive a signal from the sensors, identify grip points on the deformable laundry article suspended above the conveyor, instruct a lifter to grip and lift an identified grip point to the suspension height, determine whether the deformable laundry article is repositioned, and instruct the lifters to lower the repositioned deformable laundry article onto the conveyor.

A mobile robot includes a processor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The processor drives the mobile robot to a multiplicity of accessible two dimensional locations within a household, and commands an end effector, including at least one motorized actuator, to perform mechanical work in the household. A plurality of routines include a first routine which monitors a wireless local network and detects a presence of a network entity on the wireless local network, a second routine which receives a signal from a sensor detecting an action state of one of the network entities, the action state changeable between waiting and active, and a third routine which commands the end effector to change state of performing mechanical work based on the presence and on the action state.

A robot includes a body and a bumper. The body is movable relative to a surface and includes a first portion of a sensor. The bumper is mounted on the body and movable relative to the body and includes a backing and a second portion of the sensor. The backing is movable relative to the body in response to a force applied to the bumper. The second portion of the sensor is attached to the backing and movable with the backing relative to the first portion of the sensor in response to a force applied to the bumper. The sensor is configured to output an electrical signal in response to a movement of the backing. The electrical signal is proportional to an amount of displacement of the second portion relative to the first portion.
