  • Publication number: 20170368398
    Abstract: An improved exercise table or reformer having increased adjustability and storage features. The starting point of the carriage or platform is adjustable to accommodate different sized users. An anchor bar mechanism is adjusted to correspond to carriage starting point, and limits rotation of the anchor bar with respect to the reformer and may be non-removable from the reformer frame. A foot bar assembly may be adjusted and placed in a storage position, allowing the foot bar to serve as a lift handle. The reformer's adjustability provides greater ease of storage.

  • Patent number: 9192424
    Abstract: An AC active load device for use with a generator and a controller to supply a variable impedance when supplied with an AC waveform. The AC active load device uses a transformer and one or more transistors to generate an average max load impedance greater than 1000 ohms over varying voltage levels. The transistor functions as a dynamically-controlled resistor to the generator when the generator supplies the AC voltage to the transformer. The transistors may be GaN FETs or LDMOSFETs. The transformer steps down a voltage supplied by a generator to a voltage below the threshold voltage of the transistors. A control voltage is supplied to the gate of the transistors and may be controlled by a controller. A voltage and current are outputted to the controller from the AC active load device. The AC active load device may be used to calibrate the generator.

  • Patent number: 8052586
    Abstract: A ladder barrel for use in Pilates type exercise is disclosed. The adjustment mechanism to hold the barrel in place on the floor rail comprises a locking rail and a cam mechanism to press the locking rail into engagement with the floor rail, holding the barrel in position. The locking rail has spring biased plungers to hold it out of engagement with the floor rail when the cam is not engaged.
