A lumbar retractor according to an embodiment comprises: a first fixing part for fixing the user's lumbar regions; a second fixing part for fixing the user's pelvic regions; and a connection part disposed between the first fixing part and the second fixing part to connect the first fixing part and the second fixing part, wherein the distance between the first fixing part and the second fixing part can be adjusted by changing the length of the connection part, and the first fixing part can press each of a plurality of segments of the user's lumbar regions individually.

This disclosure relates to improved massage chairs that include air cell apparatuses. A massage chair can include at least one air cell apparatus, which can be integrated into a shoulder portion, leg rest portion, arm portion, and/or other portion of the massage chair. An inflatable air bladder can be connected to each air cell apparatus. Each air cell apparatus can transition between a retracted position and an extended position. The air cell bladder can be configured to inflate when the air cell apparatus is in the extended position, thereby securing an individual to the massage chair. Various assemblies can be used to transition the air cell apparatus between the retracted and extended positions. Other embodiments are disclosed.

A system is disclosed. The system has an accessory control module, comprising computer-executable code stored in non-volatile memory, a processor, a user device of a human viewer, a viewer accessory configured to communicate with the user device, the viewer accessory including a first motor or a first heater, a model device of a human model, and a model accessory configured to communicate with the model device, the model accessory including a second motor or a second heater. The accessory control module, the processor, the user device, the viewer accessory, the model device, and the model accessory are configured to provide a chat communication application between the human viewer and the human model configured to provide chat between the human viewer via the user device and the human model via the model device.

A compression device may include a compression plunger in operable communication with a fulcrum assembly and housing assembly in operable communication with a stepper assembly. The compression device may be constructed and arranged to allow a user to administer CPR to a patient by stepping on a portion of the stepper assembly to generate hydraulic power that may be utilized to move the compressor plunger to apply compressive force to the patient's chest. The compression device may include a housing assembly and fulcrum assembly constructed and arranged to provide for variable height and width such that patients of varying sizes can be accommodated and may receive CPR.

An apparatus including a walker and a guider attached to the walker. The guider has three sides. The first side of the three sides attaches to a front of the walker. The second side of the three sides attaches to a first side of the walker. The third side of the three sides attaches to a second side of the walker.

Walkers capable of adapting to surrounding environments, including stairs, curbs, sidewalks, and other surface or ground obstacles that have adjacent uneven surfaces. The walkers include a frame assembly having back legs, front legs, and a handlebar fixedly coupled to the back legs. Intermediate members respectively couple the front legs to the back legs and are configured for selective vertical adjustment of vertical positions of the front legs relative to the back legs and relative to at least a first surface engaged by lower ends of the back legs. After selective vertical adjustment of the vertical positions of the front legs, the front and back legs of the walker are capable of engaging and supporting the walker on the first surface engaged by the lower ends of the back legs and engaging and supporting the walker on at least a second surface engaged by lower ends of the front legs.

When a frontmost white line of a crosswalk cannot be detected due to an obstacle existing on the crosswalk, an edge position of the obstacle closer to a pedestrian in an image acquired by a camera is set as the frontmost white line of the crosswalk. As a result, a vibration generation device vibrates in a pattern that urges the pedestrian to stop at the time when the pedestrian reaches a position before the edge position of the obstacle closer to the pedestrian, so that a stop notification for walking can be appropriately performed to the pedestrian even when the obstacle exists on the crosswalk.

It is determined whether a traffic light is recognized in an image based on each of a result of a recognition operation by a traffic light first recognition unit (a recognition operation of the traffic light for an image acquired by a camera using a learned model based on pre-annotated data) and a result of a recognition operation by a traffic light second recognition unit (a recognition operation of the traffic light for an image acquired by the camera based on a feature amount of the traffic light). This makes it possible to sufficiently obtain the recognition accuracy of the traffic light, and to appropriately perform an instruction to a pedestrian according to the state of the traffic light.

Devices for improvement of the basic crutch, cane, and ambulatory aids to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries, and who frequently require using crutches for mobility. Normally, the conventional crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. Also, we show crutch support in sitting position that works as a simple and handy decompression system for herniated or bulged discs and injured/weak back muscles. An integrated crutch and walker system is described.

A lumbar decompression device may include one or more bases that support one or more uprights with a plurality of upper support members and a plurality of lower support members. The upper support members are configured to engage with a user's upper body and support a user's body weight. The one or more uprights are positioned laterally from the upper support members such that the user may perform a variety of movements of their lower body without contacting the one or more uprights.
