The disclosure provides a fit-check device and associated methods. In some embodiments, the device may be used in conjunction with a rigid or semi-rigid partially circumferential concussion-mitigating collar to determine whether the collar is appropriately sized for the user and is applying the desired amount of force to the neck veins.

An agent analysis system includes a terminal product system, a remote diagnosis system (RDS), and an agent analyzer. The terminal product system is supplied with a power source and provided with a current sensor to sense the power source. The RDS is used to transmit at least one control instruction via internet for the terminal product system. They agent analyzer is used to communicate with the terminal product system and the RDS, and configured to measure and analyze the electricity use characteristics of the terminal product system to be transmitted to the RDS; and receive and convert the control instruction from the RDS via internet for the terminal product system.

A terminal product usable time management system includes a remote server and a local apparatus. The local apparatus includes a data memory storing an identifier and an encrypted usable time of the terminal product, a microprocessor used to send a start notification of a usable time management process, a product controller used to control a product load, and a wireless networking device used to communicate with the remote server to receive a new expiry date to update the usable time. The usable time management process includes: reading the encrypted usable time stored in the data memory, decrypting the encrypted usable time, decreasing the usable time per time unit, encrypting the decreased usable time, storing the encrypted and decreased usable time into the data memory, and instructing the product controller to disable some or all functions of the terminal product, if the usable time is inaccessible or decreased to zero.

The Massage Chair System and Apparatus with Charging Kiosk includes elements for a massage chair comprised of massage system, a vending system, a charging system, and other advantageous components. The Massage Chair System and Apparatus with Charging Kiosk provide the ability to charge devices during the time a user enjoys a massage in the chair. The System and Apparatus with Kiosk has components including a timer; a power supply; and a kiosk that can attach to a chair or standalone. Once a person inserts money into the massage chair, the kiosk intercepts the amount inserted and turns on the power to the kiosk supplying power to USB ports and inductive charging pads, allowing a user to charge electronic devices.

Systems/methods for user control of a vending massage chair. The methods comprise: detecting, by the vending massage chair, when a mobile communication device is located in proximity to the vending massage chair; triggering operations by the vending massage chair to relinquish operational control to the mobile communication device, in response to a detection that the mobile communication device is proximate to the vending massage chair; receiving, by the vending massage chair, a wireless signal that was transmitted from the mobile communication device; performing operations, by the vending massage chair, to relinquish control of at least one massage chair operation to the mobile communication device in response to a reception of the wireless signal; and performing the at least one massage chair operation by the vending massage chair in response to a wireless command issued by the mobile communication device.

A far infrared (FIR) sauna cabin equipped with a far infrared (FIR) heating elements constructed of ceramic, carbon, and/or light emitting diodes (LED), designed for therapeutic use in a sauna, capable of emitting far infrared energy, and heating an individual's skin for purposes of rejuvenation, anti-aging, weight loss, and acne therapy. The FIR heating element emits IR energy in a wavelength and frequency optimum for resonant absorption by the human body, resulting in the release of toxins stored within subcutaneous fatty deposits, which are then carried out of the person's system as he or she sweats. The FIR sauna is operated by a system comprising a local control system and a remote computer running access control software. A user account is configured containing a user's allowed privileges. When a user swipes an access card, the remote computer verifies the requested privilege. If allowed, the local system energizes the sauna system.
