Abstract: A magnetic collision damping device for vehicles is disclosed, in one embodiment of which a first trough 3 and a second trough 4 are slidably connected to a vehicle frame, and electromagnets 7, 8 whose like poles are arranged to face each other are fixed inside the first trough 3 and the second trough 4. This invention can prevent the electromagnets from being damaged when being subject to an impact, and can demonstrate its collision damping function regardless of whether a collision force comes from a vehicle front or a vehicle rear. All electromagnets are arranged close to the vehicle rear, effectively protecting the safety of passengers.

Abstract: Thickness-adjustable travel pillows including travel pillows comprised of a flexible exterior cover and one or more inserts that are used to adjust the thickness and feel of the travel pillow. In some examples, the travel pillow includes multiple segments of inserts to allow a varying thickness across different portions of the travel pillow. In still further examples, the inserts themselves may vary in thickness.

Abstract: Improved foam seat cushions that are ergonomically shaped, equipped with a notch to facilitate proper sitting and to potentially center on a seat, and a plurality of channels running through the cushion to provide cooling. In some examples, the foam seat cushion includes handles located on either side and can be folded in half for easy transport. In some further examples, the foam seat cushion includes a cushioning layer disposed at the foam layer.

Abstract: An improved foam pillow including multiple foam layers, with one or more of the layers including multiple channels designed to reduce the firmness of the layer, as well as enhance cooling air flow through the pillow, thereby increasing comfort to the user by approximating the feel of a down pillow. In some examples, the improved foam pillow includes a single unified top layer equipped with channels running through its center, and optional additional layers for height adjustment. In some further examples, the improved foam pillow includes multiple layers made from different types of foam to achieve cost savings. In still further examples, channels are provided in multiple layers to maintain a desired comfort and feel.

Abstract: An arthritic hand or foot treatment apparatus and system for applying dried, pressurized and/or heated air to a user's hand or foot.

Abstract: A warning alarm diaper device including a moisture detecting device and a warning alarm device. Preferably, the diaper and moisture-detecting device are disposable, and the warning alarm device is reusable.

Abstract: A bottle cap turning device for untightening or tightening a bottle cap during an opening operation or closing operation, respectively. The bottle cap turning device preferably progressively engages and further grips the bottle cap when the bottle cap turning device is twisted until the bottle cap begins to rotate during the opening operation or until the bottle cap stops rotating and is fully tightened on the bottle.

Abstract: The present invention relates to a multifunctional and portable solar charger, more particularly, to a portable solar charger which combines the functions of charging, illumination and power supply together in order to perform effectively transform between a low voltage and a high voltage and conversion between chemical energy and electrical energy, when a storage battery of the charger is charged with the electrical energy, the electrical energy can be transferred to a mobile phone or its battery and other mini-type electrical apparatus such as digital camera, portable computer and portable CD player, in addition, the charger can be connected to an alternating current (AC) power supply.

Abstract: In one embodiment the present invention provides for a system and method of transferring the heat of used coolant to source coolant by the use of a heat exchanger. A portion of the used coolant is passed through a regenerative heat exchanger where the heat from the used coolant is transferred to the source coolant. The amount of heat exchanged may be controlled by the amount of used coolant that is passed through the regenerative heat exchanger, where the remainder of the used coolant is discharged by conventional techniques.
