Improvements to a desk and exercise semi-recumbent bicycle is disclosed, the desk allows a person exercising while utilizing the desk with a computer, as a table or read a book. The desk has a 6-way adjustment relative to the seat for elevation of the desk, angle, sliding forward and backward of the desk or the proximity of the desk relative to the chair and or the pedals. The desk pivots to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle. The dimension from the seat to the pedals is adjustable to accommodate these different desires. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. A recording mechanism can count distance, elapsed time, calories or other information.

A system for transmitting power and data between two circuit boards may include a fixed circuit board having a primary coil and a rotatable circuit board having a secondary coil. The system may further include a sensor in communication with the secondary coil of the rotatable circuit board. The fixed circuit board's primary coil may be inductively coupled to the secondary coil and may provide power and receive data from the sensor when inductively coupled to the secondary coil.

An angle adjusting mechanism includes a first bracket and a second bracket hinged to each other. The second bracket is provided with two arc-shaped position-limiting slots, and a set of position-limiting holes is arranged in the position-limiting slots. A diameter of the position-limiting holes is larger than a slot diameter of the position-limiting slot. A bolt passes through the first bracket and the position-limiting slots and is movable along the first bracket and the position-limiting slots. An end portion of the bolt is provided with an adjusting segment and a position-limiting segment. A diameter of the adjusting segment is smaller than a diameter of the position-limiting segment. The adjusting segment and the position-limiting slot are engaged to adjust an angle of the second bracket relative to the first bracket. The position-limiting segment and the position-limiting holes are engaged to fix the first bracket and the second bracket after adjustment.

An exercise support apparatus is capable of supporting exercise taken by a patient during blood purification treatment and includes an estimation generating device that generates an estimation representing a circulating-blood-volume rate of change regarding a circulating blood volume that is estimated to be observed after the exercise is started, the estimation being generated after the blood purification treatment is started and from a continuous measurement of the circulating-blood-volume rate of change as regarding changes in circulating blood volume that is conducted before the exercise is started; a calculating device that calculates a difference between a measured value of the circulating-blood-volume rate of change that is acquired after the exercise during the blood purification treatment is started and a value of the estimation generated by the estimation generating device; and a first monitoring device that monitors whether the difference or ratio calculated by the first calculating device is over a predetermined threshold.

A computer-implemented system may include a treatment device configured to be manipulated by a user while the user is performing a treatment plan, a patient interface. and a computing device configured to: receive treatment data pertaining to the user who uses the treatment device to perform the treatment plan; identify at least one enhanced component using the treatment data; generate an enhanced environment using the at least one enhanced component and the treatment plan; output at least one aspect of the enhanced environment to at least one of the patient interface and another interface; receive subsequent treatment data pertaining to the user; and selectively modify at least one of the enhanced environment and at least one of the at least one aspect of the treatment plan and any other aspect of the treatment plan using the subsequent treatment data.

An inclined exercise apparatus may include a support frame, pedals and arm supports for a user. The angle of incline of the inclined exercise apparatus may be adjusted to be increased for a decreased level of difficulty and decreased of an increased level of difficulty. The inclined exercise apparatus may include a chest support for supporting a user's chest. The inclined exercise apparatus may include arm supports and hand grips so that a user can adjust their body position while using the inclined exercise apparatus.

Hand pedals for turning the crank set of an arm driven tricycle have modular interchangeable components including a bearing which mounts on the spindle of the crank. A bridge connects the bearing to a handle. The bridge has two legs connected by a transverse spar. Different bridges and handles may be used having different sizes, shapes, lengths and angular orientations which allow the hand pedals to be customized to accommodate a particular user. Hand pedals may also be used on hand cranked bicycles, stationary hand cranked bicycles and industrial equipment.

An angle adjusting mechanism includes a first bracket and a second bracket hinged to each other. The second bracket is provided with two arc-shaped position-limiting slots, and a set of position-limiting holes is arranged in the position-limiting slots. A diameter of the position-limiting holes is larger than a slot diameter of the position-limiting slot. A bolt passes through the first bracket and the position-limiting slots and is movable along the first bracket and the position-limiting slots. An end portion of the bolt is provided with an adjusting segment and a position-limiting segment. A diameter of the adjusting segment is smaller than a diameter of the position-limiting segment. The adjusting segment and the position-limiting slot are engaged to adjust an angle of the second bracket relative to the first bracket. The position-limiting segment and the position-limiting holes are engaged to fix the first bracket and the second bracket after adjustment.

An exercise machine of the type which have pedals or foot plates through which a person can, in use, transfer kinetic energy to the machine is described. In embodiments the exercise machine is configured such that the pedals or foot plats vibrate during exercise.

This application describes a mobile cycling apparatus which may be easily installed in transportation terminals (and/or other locations) to provide people with an opportunity to exercise. The mobile cycling apparatus described herein may mounted proximate existing seating in the transportation terminals. In some examples, the mobile cycling apparatus may be coupled to the seating, such as a beam seating platform, and/or tables proximate a chair. In some examples, the mobile cycling apparatus may be directly coupled to the floor or other substantially horizontal surface. In some examples, the mobile cycling apparatus may be detachably coupled to a surface (e.g., seating, table, floor, etc.). In such examples, the mobile cycling apparatus may be moved between locations in the transportation terminal.
