A neck pillow includes: a cushion portion worn on a user's neck and an electro-liquid driving unit mounted into the cushion portion, being bent in a shape of an arc, and including ferroelectric particles, each having an electrorheological property, and nonconductive liquid. The electro-liquid driving unit generates vibration by contraction and expansion that are repeated when an arrangement of the ferroelectric particles and the nonconductive liquid is changed according to whether drive current is applied. A low voltage power supply unit supplies low voltage electricity necessary to drive the electro-liquid driving unit and a high voltage control circuit unit converts low voltage direct current into high voltage direct current and supplies the drive current to the electro-liquid driving unit and adjusting micro-current to generate target vibration in the electro-liquid driving unit.

Arrangements described herein relate to systems, apparatuses, and methods for a headset system that includes a transducer configured to collect physiological data of a subject, a device housing configured to support the transducer, an insert portion disposed on the device housing, a support structure comprising a baseplate and a receiving portion, and a head cradle supported by the baseplate. The receiving portion extends in a direction that is oblique with respect to the baseplate. The insert portion is sized and shaped to engage the receiving portion to removably attach the device housing to the baseplate.

An electromotive adjusting device for adjusting the inclination of a seat part of an item of seating furniture includes a mounting bracket for connecting to a body element of the item of seating furniture and a motor and transmission unit embodied as a drive unit. A mounting element secures the seat part of the item of seating furniture. The motor and transmission unit includes a rotatable drive element and is securely fixed to the at least one mounting bracket.

The invention provides head and neck support sleep aid devices and methods for securely restraining the head of fatigued and sleeping travelers seated in a constrained, upright position, to prevent involuntary forward or lateral head flexion. The devices and methods of the invention employ a rigid elongate lever member adapted to be interposed between a user's back and an upright seat surface and head bracing means connected to the lever member to restrain the user's head against forward and lateral flexion.

A balancing pressure bearing apparatus including a connecting base and bearing components is provided. Inside the connecting base is any material selected from a volume-incompressibe fluid, semifluid and elastic element, and arranged thereabove is each bearing component. The bearing components have bearing surfaces for supporting any pressing-down human body part and pressure reduction. When the connecting base is pressed down, a Pascal phenomenon is generated for a pressure applied to the fluid, semifluid or elastic element inside the connecting base to be transmitted equally in all directions. Each portion thereof has the same pressure for balancing pressure of the supportive bearing surfaces pressed by any two human body parts, thereby reducing and balancing pressures thereon to achieve a more comfortable contact sensation of pressure release and a correct posture effect. Hence, the invention can serve as a cushion, seat, backrest, mattress or pillow product.

A removable headrest cover includes a flexible shroud having an inner chamber and an outer chamber. The inner chamber contains padding and is separated from the outer chamber by an inner panel and the outer chamber is accessible through an outer opening defined through an outer surface of the shroud. The shroud is configured to enclose a chair headrest within the outer chamber, and when removed from the chair, to be rolled or folded into multiple stacked portions the outermost portion of which includes an end segment of the outer opening that can enclose the other rolled or stacked portions within the outer chamber to form a pillow.
