A pliable band or hoop that is flexible to normal handling, but cannot stretch circumferentially once it has reached the limits of its circumferential length. The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.

Anterior cruciate ligament (ACL) is the most commonly injured knee ligament in sports-related activities, especially in pivoting sports. Considering that the knee is free to flex / extend but has much more limited motions about the off-axis (tibia rotation and valgus / varus), ACL injuries are often associated with excessive off-axis loadings. A pivoting / sliding mechanism combined with sagittal plane movement / exercise is described as a diagnostic tool to evaluate off-axis neuromechanical and anatomical risk factors of noncontact ACL injuries. The pivoting / sliding mechanism is also described as an intervention tool for off-axis training, possibly based on the diagnosis, to reduce the incidence of ACL injuries. Training outcome can also be evaluated using the pivoting / sliding mechanism. In general, the pivoting / sliding mechanism can be used with many sagittal plane exercise machines and used to improve off-axis control of the lower limbs and reduce lower limb injuries.

Two sensible thermal energy storage (STES) systems in multiple chambers containing molten eutectic salts have been devised for use at temperatures above 565° C. For the first type, the thermal energy of low specific heat of an immiscible gaseous heat transfer fluid (HTF) at temperatures above 900° C. is readily converted to dispatchable heat of high specific heat in the molten eutectic salt liquid layers operating at high temperatures, which can again produce a gaseous HTF at a constant temperature of 700° C. or higher for the lower electricity generation capacities. For the second type, the molten eutectic salt liquids are used as a thermal energy storage (TES) medium and also a HTF at temperatures above 700° C. for the higher electricity generation capacities. These STES systems provide an effective cushion against the disturbances of heat supply from the sun.

A method for control of electrochromic devices is revealed. First a duty cycle of PWM is changed to a preset Q value according to a signal detected by a detector while the electrochromic device is switched to the colored state. The Q value represents electric charge that corresponds to colored-state transmittance. Then turn off the PWM. Thus the response time for coloration and the transmittance of the electrochromic device are maintained within a preset range, without being affected by ambient temperature, setting time and aging of the materials used. Thus the electrochromic device is more convenient to use and having more practical value.
