Abstract:
The present invention provides a novel implementation of a low cost eccentric mass motor vibrotactile transducer providing a point-like vibrational stimulus to the body of a user in response to an electrical input. Preferably the eccentric mass and motor form part of the transducer actuator moving mass. The actuator moving mass is constrained into vertical motion by a spring between the actuator housing and moving mass. The actuator moving mass is in contact with a skin (body) load. The actuator housing is in simultaneous contact with the body load. The body load, actuator moving mass, spring compliance and housing mass make up a moving mass resonant system. The spring compliance and system component masses can be chosen to maximize the actuator displacement and/or tailor the transducer response to a desired level. The mass of the motor/contactor assembly, mass and area of the housing, and the compliance of the spring are chosen so that the electromechanical resonance of the motional masses, when loaded by the typical mechanical impedance of the skin, are in a frequency band where the human body is most sensitive to vibrational stimuli 150-300 Hz. This configuration can be implemented as a low mass wearable vibrotactile transducer or as a transducer that is mounted within a soft material such as a seat. A particular advantage of this configuration is that the moving mass motion can be made almost independent of force loading on the transducer housing.
Abstract:
An adjustable bed frame assembly includes a center frame comprising two substantially parallel side frame members connected by two substantially parallel connector frame members. The adjustable bed frame assembly also includes a base frame that includes a plurality of legs for mounting on a floor is rigidly affixed to the center frame. The adjustable bed frame assembly further includes a head frame that comprises two substantially parallel side frame members connected by at least one connector frame member. The adjustable bed frame assembly also includes an actuator for raising and lowering the head frame.
Abstract:
Aspects of this invention relate to an adjustable bed frame assembly that includes a first frame that includes two substantially parallel side frame members and at least one connector member between the parallel side frame members, a second frame comprising two substantially parallel side frame members, each of the side frame members having a lower end pivotally attached to one of the at least one connector member of the first frame, a bracket that includes a sliding slot, where in the bracket is securely attached to the second frame; and an actuator with a first end pivotally attached to the first frame and a second end that is slidably connected to the sliding slot of the bracket, wherein, when the actuator extends or retracts, the second end travels within the sliding slot without moving the second frame until an extent of the sliding slot is reached.
Abstract:
A controller for an adjustable bed manages at least one wireless communication function, such as Bluetooth, IEEE 802.x, and peer-to-peer functions in association with controlling the bed. The controller also can control a second system associated with the adjustable bed.
Abstract:
Transducers and resonators are embedded in body support structures in contact with a user to for the purpose of conveying musical sound energy to a user's body at selected frequencies and in selected patterns. Body support structures comprise beds, pillows, chairs, and other structures typically used to support people. The sound may be audio tones and/or music. The transducers and resonators may be incorporated into a foam component or in a coil spring component of the body support structure. Latex-type foams and beds made with springs are candidate body support structures for receiving transducer's and resonators. Electro-active polymers are also used as transducers.
Abstract:
An object of the present invention is to provide an air cell which is capable of detecting that the upper end side and the lower end side of the air bag are nearer than a predetermined distance. This air cell has an air bag, a base member to which the lower end portion of the air bag is attached, an air chamber AR configured by the air bag and the upper surface of the base member, a thin film portion which forms the bottom surface of the air chamber and capable of deforming elastically in the up-and-down direction, an extending member configured to extend upwardly from the upper surface of the thin film portion, detecting means which is provided under the thin film portion and which detects downward deformation of the thin film portion.
Abstract:
An air-tight foam-filled bladder is used for varying massage intensity in a massage chair, massage mat, or other massage device. The bladder may be compressed from a default or relaxed thickness by evacuating air from the bladder. The thickness of the foam-filled bladder may be reduced to a collapsed thickness in which the foam is compressed within the bladder. In use, the foam-filled bladder is placed proximate a conventional fixed massage mechanism in a massage device, such as in the back rest of a massage chair. By controlling the amount of air evacuated from the bladder, the intensity of the massage is controlled by varying the amount of pressure exerted by the fixed massage mechanism on the user. In the case of a massage chair, the user may advantageously sit back in the chair without discomfort when the user does not want a massage, and may control the intensity of the massage provided by the chair. In another embodiment, an active pump may be used to inflate one or more bladders that may or may not include a foam insert. The number, size and location of the bladders may be varied in any of the embodiments.

Abstract:
Method, procedure, and device for applying tactile sensation and vibration to the human body. In this invention one or more vibrating elements emit sine waves between 20 and 800 Hz. These waves are varied in frequency, amplitude and rhythm to create in the subject the sensation of massage moving through different parts of the body even though the signal emitter may be a point source.
Abstract:
A massage mechanism with a moveable massage set having a biased movement is installable in a massage chair or a massage bed, a standard chair or a mattress, and so forth, which provides a massage to multiple massage areas. Each massage element is composed of two biased, separated and correspondingly symmetric swing arms and two massage wheels disposed on the same surface side of two ends of the swing arms; when massage set is turned on, the spindle drives the swing arm with a biased rotation so that the massage wheels simultaneously provide a massage effect to the insides and outsides of both legs.
