Abstract: This application describes a microfluidic system for measuring blood flow velocity using particle image velocimetry (PIV) and wavelet-based optical flow velocimetry (wOFV) processing to determine one or more hemodynamic parameters. The hemodynamic parameters can include whole blood rheology as well as spatiotemporal variations in blood velocity, respectively, during coagulation in flowing blood samples. The system can provide quantitative information on the formation and evolution of thrombi, identify subjects with clotting disorders associated with abnormal thrombus growth rate, and/or determine the effect of therapeutics and/or therapeutical approaches on clotting dynamics and thrombus formation.

Abstract: An apparatus having a first sliding member having an outer wall surface and an inner wall surface defining a central opening. A second sliding member having an outer wall surface and that is configured for sliding insertion into the central opening of the first sliding member. A space is formed between first and second sliding members. The first sliding member slides and may be fixed at a selected location along the length of the second sliding member. The apparatus includes a slider insert having a center section and a pair of lips that engage the first sliding member for removably mounting the slider insert to the first sliding member such that the slider insert is located in the space between the first sliding member and the second sliding member. The slider insert slides with the first sliding member and prevents the first and second sliding members from contacting on another.

Abstract: An apparatus having an accessory carrier that slides along an exercise rack and repositions an accessory through one-handed operation. A stationary handle fixedly mounts to the accessory carrier by first spacers. A moving handle mounts to the accessory carrier by second spacers. Each second spacer includes a barrel having an open end a closed end. A shaft extends through the barrel and the closed end and is mounted to the moving handle. As the moving handle moves to an engaged position, a pin end of the shaft slides out of the open end of the barrel and engages the exercise rack. This engagement prevents relative movement of the accessory carrier with respect to the exercise rack and fixes the accessory carrier at a selected position. A biasing member biases the moving handle to automatically engage the pin end and lock the accessory carrier in place.

Abstract: An exercise apparatus includes two or more vertical rack members. Tracks on the rack members include an elongate carrier guide extending substantially along the length of the track and a notched retention bar. An accessory carrier, having an accessory removably mounted thereon, slides vertically along the carrier guide. A carrier lock is mounted to the accessory carrier at a pivot point and has a handle located on one side of the pivot point and a locking tip on the opposite side of the pivot point for selectively engaging a notch of the retention bar for securing the accessory carrier at a selected position. The carrier lock rotates between locked and unlocked positions. When locked, the locking tip is located within a notch and prevents the accessory carrier from sliding along the carrier guide. In the unlocked position, the accessory carrier can freely slide along the carrier guide.

Abstract: A mobile exercise device having a front wheel connected via a front wheel mount to a weight carriage that extends rearwardly from the front wheel mount. A weight loading member is mounted to the weight carriage and is operable to receive exercise weights and to support the exercise weights so that the exercise weights move as the weight carriage moves. A user engagement member includes a first end for engaging hips of a user and a second end for connecting to the weight carriage. Lifting the weight carriage via the user engagement member causes the weight loading member to be lifted and to rotate with respect to the front wheel.

Abstract: A vapor dispensing device is provided which is less noticeable as a dispensing device to observers of the device. For example, in this context, the dispensing device may have the general appearance of a standard electrical wall outlet and have the ability to use the outlets into which the dispensing device is plugged.
