An electronic device includes a first portion, a joint, a second portion adjustably connected to the first portion at the joint, a cable extending from the first portion to the second portion through the joint, and a processor electrically connected to the cable and a memory component storing electronic instructions that, when executed by the processor, configure to the electronic device to transmit data through the cable, the data having a bit error rate, and determine a position of the first portion relative to the second portion based on the bit error rate.

Position sensor

A support surface includes a table top, moving portions, base portions, and sensors. The moving portions are configured to move the table top in multiple degrees of freedom. Each moving portion is configured to move the table top in a degree of freedom and prevent movement of the table top in other degrees of freedom. The base portions are coupled to the moving portions and are configured to support the moving portions. The sensors are configured to receive a user input and communicate the user input to the moving portions so that the moving portions move the table top based upon the user input.

Movable support surfaces

A support surface includes a table top, a movement stage, a movement actuator, a first sensor, a second sensor, and a controller. The movement stage is coupled to the table top and configured to couple to a structure. The movement stage is further configured to permit the table top to move in a degree of freedom. The movement actuator is operable to move the table top in the degree of freedom. The first sensor is for receiving a first user input. The second sensor is for receiving a second user input. The controller operates the movement actuator to move the table top according to the first user input received by the first sensor when the second user input is simultaneously received by the second sensor.

A high performance, low-cost passive prosthetic knee includes one or more modules to enable able-bodied gait by transfemoral amputees to improve metabolic efficiency and reduce stigma from conspicuous abnormal gaits. A stance stability module includes a latch with a virtual lock axis that automatically locks and unlocks. An early stance flexion module enables able-bodied gait during stance. Hydraulic fluid dampers ensure reliable swing phase control. A swing extension energy storage module stores and returns energy as the knee locks and unlocks, respectively. These modules may be used together, in any combination, or individually.

Devices, systems, and methods of the present disclosure are directed to accurate and non-invasive assessments of anatomic vessels (e.g., the internal jugular vein (IJV)) of vertebrates. For example, a piezoelectric crystal may generate a signal and receive a pulse echo of the signal along an axis extending through the piezoelectric crystal and an anatomic vessel. A force sensor disposed relative to the piezoelectric crystal may measure a force exerted (e.g., along skin of the vertebrate) on the anatomic vessel along the axis. The pulse echo received by the piezoelectric crystal and the force measured by the force sensor may, in combination, non-invasively and accurately determine a force response of the anatomic vessel. In turn, the force response may be probative of any one or more of a variety of different characteristics of the anatomic vessel including, for example, location of the anatomic vessel and pressure of the anatomic vessel.
