The present invention includes a retractable signaling apparatus and a method of using the apparatus to alert passers-by to the presence of a stationed vehicle that may be obscured from view. In situations that include the parking of a small vehicle or the stationing of such a vehicle along a road due to mechanical difficulties, it is often difficult for passers-by, including pedestrians and other motorists, to be aware of the presence of the vehicle. In such situations the present invention provides an easily carried signaling device that can be tethered to the vehicle. The signaling device provides an alert to passers-by of the presence of the vehicle in a timely manner such that collision with the vehicle can be avoided. The tethering means ensures that the alert is maintained in view of ambient conditions or mischief that could otherwise cause the loss of the alerting device.

A fan assembly for creating an air current includes an air inlet, an air outlet, an impeller, a motor for rotating the impeller to create an air flow passing from the air inlet to the air outlet, the air outlet comprising an interior passage for receiving the air flow and a mouth for emitting the air flow, the air outlet defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth, a control circuit for controlling the motor, a remote control for transmitting control signals to the control circuit, and at least one magnet for attaching the remote control to the air outlet.

Disclosed herein are muscle-back iron golf clubs that have improved mass qualities to provide higher rotational moments of inertia and lower center of gravity while retaining the workability of muscle-back irons and the size, shape and dimensions preferred by tour players and low handicap players.

A weight-adjustable golf club head includes a rear lightweight covering and a golf club head body combined therewith. The rear lightweight covering has a rear crown portion and a rear wall portion extended therefrom. The golf club head body is combined with the rear lightweight covering which is designed to have a striking face, a front crown portion and a sole portion. The rear lightweight covering is made from a low specific gravity metal, and is designed to have a thickness less than 0.6 mm. The rear lightweight covering has an inner surface formed with a plurality of reinforcing ribs.

A golf club head comprises a main body and a crown cover disposed in a crown portion of the head, wherein the main body comprises a crown base made of a metal material and provided with a plurality of openings gradually decreasing in the opening area from the backside to the foreside of the head, and the crown cover is made of a material such as FRP whose specific gravity is lower than the metal material, and disposed on the crown base so as to cover the openings.

A golf club head is mainly consisted of a metallic head housing having and a nonmetallic crown. The metallic head housing, which hollow and is open at a top thereof, has a face, a sole, a rear, a toe and a heel. At the toe and the heel of the head housing is a gap respectively. The crown coupled to the top of the head housing, wherein the crown has two arms coupled to the toe and the heel of the head housing respectively to shield the gaps.

Aspects of an embodiment of a check valve turbine assembly include a rotation platform having an axis of rotation, a vertical member concentrically secured to the rotation platform about the axis of rotation, a rotatable sail assembly attached to the vertical member that includes a frame, a hinge beam, and a rotatable sub-sail assembly. The sub-sail assembly includes a stem beam, a sub-sail grid frame attached to the stem beam, and a plurality of flaps rotatably attached to the sub-sail grid frame and configured to move between a closed position and an open position relative to the sub frame. Aspects of a marine check valve turbine include a free-floating platform structure configured with an upper surface at or near a water surface and a vertical member secured to the platform structure about an axis of rotation and configured to extend from the upper surface of the platform structure.

A low profile acoustic array (10) is configured to selectively respond to shear waves while rejecting compression wave energy in the frequency range of interest. One sensor array is configured as a linear strip with a frame segment having at least one longitudinally extending rail and a plurality of sensor elements (20) extending therefrom. These sensor elements have a resilient core and opposing PDVF outer layers configured with opposing polarities onto the core. The linear strip array also includes a pair of separate electrical signal transmission paths. The transmission lines can include a series of undulations formed thereon to help minimize undesired mechanical crossover between sensors. A carrier member can be configured to be detachably releasable carries the discrete sensors to maintain the positional alignment until they are secured to a patient.

The iron golf club head (20) of the present invention is preferably composed of three main components: a periphery member 22, a central member 24 and a face plate 26. The periphery member (22) is preferably composed of a high density material such as a nickel-tungsten alloy. The central member (24) is preferably composed of a lightweight, non-metal material. The face plate (26) is preferably composed of a titanium alloy material. The iron golf club head (20) preferably has high moments of inertia Izz and Ixx.

A plastic, blow-molded, disposable water bottle adapted for use with a dispenser, said bottle having a basically spherical or elliptical shape, a footed base portion, and a unique neck geometry.

A method of making a mounting patch for mounting an electronic assembly in the inner liner or a pneumatic tire includes the steps of providing a power source, embedding the power source into a quantity of uncured rubber, and curing the uncured rubber by applying sufficient heat and pressure to the uncured rubber such that the power source is secured in the rubber. The provided power source may correspond to one or more batteries. Additional components that may be incorporated with the mounting assembly may include at least one conductive element, which may also be embedded into the quantity of uncured rubber. An antenna may be configured with undulations to allow longitudinal stretching of the antenna and then also embedded into the quantity of uncured rubber. A preferably non-conductive adhesive layer may be applied to selected portion of the power source, conductive element, and/or the antenna before the step of embedding in the uncured rubber.

A wearable lower-limb assistance exoskeleton comprises a left-side leg (A), a right-side leg (C) and an object carrier (B). A left first connecting rod (A1) is matched with an inserting rod (B1) to fixedly connecting the left-side leg (A) with the object carrier (B), and a right first connecting rod (C1) is matched with the inserting rod (B1) to fixedly connecting the right-side leg (C) with the object carrier (B). Lower limbs on two sides totally have two rotating degrees of freedom, and the lower limb on each side has one degree of freedom, so that hip joints, knee joints and ankle joints can rotate around the frontal axis. A left motor (A20) and a right motor (C20) are controlled by a bionic intelligent control program to realize walking gaits of the wearable lower-limb assistance exoskeleton. By the wearable lower-limb assistance exoskeleton, physical ability consumption of a person can be effectively reduced. The wearable lower-limb assistance exoskeleton is used for lower-limb assistance, can be used for soldier fighting equipment for military use and can also be used in the field of lower-limb rehabilitation.
