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.

A device (100) for traversing a suspended cable (110) anchored at each end, and the device comprising: an open non-linear channel (130) for receiving, by a slotting action, the suspended cable, said non-linear channel defining a minor segment (165-2); a motor (135); and a drive mechanism (140), powered by the motor, arranged within the minor segment so as to contact the suspended cable when received by the non-linear channel and thereby to drive the device along the suspended cable.

Described herein are methods of fabricating heat exchangers and heat source assemblies using electrochemical additive manufacturing (ECAM). A method may comprise submerging a build plate (e.g., a base and / or a heat source) and a printhead into an electrolyte and selectively activating an electrode subset of the printhead thereby electrochemically depositing a heat-exchanging portion. In the final assembly, the average coefficient of thermal expansion (CTE) of the base is closer to that of the heat source than the average CTE of the heat-exchanging portion. The combination of the heat-exchanging surfaces and the base forms openings (e.g., non-linear channels) for directing a heat transfer fluid through the heat exchanger. The openings may extend to the base and / or to the heat source for direct contact. For example, any dimension of each extension end may be less than a critical dimension, determined by adhesion, CTE mismatch, and temperature fluctuations.

A finFET is presented that includes a nonlinear channel. The nonlinear channel includes one or more arcuate, curved, segmented, or the like sidewalls that define a channel width and a channel length. The nonlinear channel provides a relatively increased channel length compared to a linear fin oriented perpendicular to the gate width. Thus, the channel length of the nonlinear channel can be relatively increased within the boundaries of the gate. In other words, the relatively increased channel or fin length within the footprint of the gate can limit short-channel effects by suppressing the electric field along the nonlinear channel.
