摘要： Various implementations include a spotting device for supporting a barbell, the spotting device including a base and an arm. The base has a base body with first end and a second end, at least one foot coupled to the second end of the base body, and a base longitudinal axis. The arm has an arm body with a first end and a second end, a coupler coupled to the first end of the arm body, and an arm longitudinal axis. The coupler is couplable to a portion of a barbell. One of the first end of the base body and the second end of the arm body defines a body opening extending partially through the one of the base body or the arm body, and the other of the second end of the arm body and the first end of the base body is slidably disposed within the body opening.

摘要： Methods and systems for producing a three-dimensional structure using electrochemical additive manufacturing are described herein. The methods can comprise injecting a growth control solution into an electrolyte comprising a metal salt to form a growth control region and applying an electric potential to a working electrode to thereby form a layer of metal at a location defined by the growth control region. The injecting and applying steps of the methods can be repeated for form the three-dimensional structure on a layer-by-layer basis.

摘要： Various implementations include an assistive hamstring device including a belt, knee sleeve, first elastic strap, second elastic strap, and third elastic strap. The first elastic strap extends between a first dorsal belt portion of the belt located adjacent a sagittal plane on a dorsal side of the person and a lateral knee portion of the knee sleeve located adjacent a lateral side of the knee. The second elastic strap extends between a side belt portion of the belt located adjacent a coronal plane of the person and a medial knee portion of the knee sleeve located adjacent a medial side of the knee. The third elastic strap extends between a second dorsal belt portion of the belt located between the first and side belt portion and an intermediate dorsal knee portion of the knee sleeve located between the lateral and medial knee portion, along the dorsal portion of the knee.

摘要： In an embodiment, a non-contact chewing sensor is provided. The chewing sensor includes an optical proximity sensor specifically designed to monitor chewing. An IR emitter/receiver pair of the chewing sensor may be positioned over a muscle of a user that is involved in the chewing process such as the temporalis muscle. The IR emitter of the sensor emits IR light onto the surface of the skin covering the muscle where it is reflected. When the user chews, the amount of light that is received by the IR receiver changes due to the activation of the muscle. The amount of light received can be used as a signal to determine when the user is chewing and likely eating.

摘要： Wirelessly distributed and multi-directional power transfer systems and related methods are described herein. An example system for distributing power across a wireless medium can include a plurality of wireless modular power packs connected across a wireless medium to a wireless power receiver circuit that is connected to a load. Each wireless modular power pack can include a respective wireless power transmission circuit directing a respective wireless power signal to the wireless power receiver circuit. The system can also include a power source positioned within each of the wireless modular power packs. Each power source transmits a respective power signal across an internal power interface to a respective wireless power transmission circuit within a respective wireless modular power pack.

摘要： A slotted Substrate Integrated Air Waveguide (slotted SIAW) antenna array comprising a ground plane having a reflective planar surface formed of a conductive material; an air waveguide structure fixably attached to, or formed onto, the reflective surface of the ground plane and having a slotted aperture defined, in part, by two conductive side walls that terminates at a conductive end wall, where a portion of the conductive side walls and a portion of the conductive end wall define an aperture-facing radiative conductive surface of the aperture and electrically couples with a conductive antenna feedline; and a slotted cover plate fixably attached to, or formed onto, the slotted-waveguide structure and having an area that fully covers the slotted aperture and has two or more radiating slotted apertures coincident to the slotted aperture and to the reflective planar surface of the ground plane.
