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.

The system comprises an outer sheath arranged and configured to form a passageway for the intracorporeal device and/or the insertion device. The outer sheath guides the insertion device. A method of transcatheter insertion with the system is also provided.

Abstract: Methods, apparatus, and systems are provided for scanning and measuring an anatomical cavity. An apparatus may include an absorbing medium assembly that is fluidly connected to an earpiece and configured to provide an absorbing medium to the earpiece. The absorbing medium assembly may include a medium container with a gas trap, as well as a tube fluidly connected to the medium container. The gas trap may be located at a top portion of the medium container. The tube may be coupled to the top portion or a bottom portion of the medium container. The system may include a dip tube disposed inside the medium container when the tube of the absorbing medium assembly couples to a top portion of the medium container. A gas relief valve configured to enable gas to escape may also be present in the apparatus.

Abstract: An acoustic enhancement device improves the built-in sound system of electronic devices with speakers, such as smart phones, tablets, laptops and the like. The acoustic enhancement device can channel sound waves toward a particular direction—toward the listener's ear—thereby resulting in more sound waves reaching the listener. The acoustic enhancement device can also boost the acoustic impedance of the speaking, resulting in a stronger, specific power or volume. With the device's unique shaped design, the narrow openings of the speaker holes are proportionately opened toward the wider end of the device, thereby reducing the effect of wave reflection and increasing the sound volume toward the listener's ear.

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 two-piece mobile device holder having a case assembly and a mounting assembly is disclosed. The case assembly is configured to receive and secure a mobile device such as a smart phone. The mounting assembly is configured to be detachably coupled to other objects. Sets of permanent magnets are arranged in a circular pattern in the case assembly and the mounting assembly. The magnets in both the first and second set of magnets are arranged with alternating magnetic polarity. As the case assembly is placed on top of the mounting assembly, the magnets in the mounting assembly will attract magnets with opposite polarities in the case assembly. A user may detach the case assembly from the mounting assembly by rotating the case assembly such that the magnets in the case assembly are now adjacent to magnets in the mounting assembly of the same polarity.
