Abstract: In one embodiment, a photovoltaic cell comprises a transparent substrate having an exposed bottom surface for receiving light; a transparent-conducting-oxide layer positioned over the transparent substrate; a chalcogenide photovoltaic-absorber layer positioned over transparent-conducting oxide layer; and another transparent-conducting-oxide layer positioned over the photovoltaic-absorber layer, where the photovoltaic cell is operable to transmit incident light to both sides of the photovoltaic-absorber layer and to absorb incident light at both the top side and the bottom side of the photovoltaic-absorber layer.

Abstract: A remote control is arranged for controlling an air swimming toy includes a toy body and an operation system for shifting an altitude of the toy body and for steering a direction of the toy body. The remote controller includes a hand-held housing adapted for being held by a user's hand, a circuit control which is received in the hand-held housing and is wirelessly linked to the operation system, and a gyro-balancer control built-in with the circuit control to detect an orientation of the hand-held housing, wherein the operation system is controlled by the circuit control in response to the orientation of the hand-held housing to concurrently control the altitude and direction of the toy body in the air.

Abstract: A finger glove for a touch screen of an electronic device includes a finger pocket adapted for being worn by a finger of a wearer, and a touch receptor which is made of electro-conductive material. The finger pocket has a tip portion covering a distal phalanx of the wearer's finger and a finger stall portion extended from the tip portion. The touch receptor is provided at the tip portion of the finger pocket at an outer surface thereof for responsively contacting with the touch screen of the electronic device.

Abstract: An air swimming toy includes a toy body having a floating body and a tail body, a steering device including a motorized unit for generating a reciprocating power transmitting to the tail body so as to generate a wiggling motion thereof, and a remote controller remotely controlling the steering device to operate the motorized unit, wherein said motorized unit is activated to directly drive the tail body to move in order to steer and propel the toy body. In particular, the reciprocating power is directly transmitted from the motorized unit to the tail body via a gear unit to precisely and smooth drive the tail body moving in a wiggle motion.

Abstract: An air swimming toy includes a toy body, a driving device including an air propeller supported at a bottom side of the toy body for creating an air dynamic underneath the toy body, and a remote controller remotely controlling the driving device to operate the air propeller, wherein the air propeller is activated to rotate in order to control an altitude of the toy body via the air dynamic. In particular, when a controllable air pressure underneath the toy body is lesser than a surrounding air pressure, the toy body is elevated in the air, and when the controllable air pressure is higher than the surrounding air pressure, the toy body is dropped down in the air.

Abstract: A remote actuation device for a toy helicopter remotely controlled by a remote controller includes a motorized unit and an actuation unit. The motorized unit is powered by a power source of the toy helicopter. The actuation unit, which is arranged to couple with the toy helicopter, is operatively linked to the motorized unit for generating multiple actions, wherein the motorized unit is controlled by the remote controller for enabling the remote controller operating the actuating unit to select the multiple actions. Therefore, the operator of the toy helicopter is able to control the remote controller to select the action of the actuation unit to be operated.

Abstract: A toy helicopter includes a body, a rotor arrangement for generating a rotational power, and a foldable propeller blade including a bracket member coaxially mounted to the rotor arrangement and at least two blade leafs pivotally and symmetrically coupling with the bracket member in a horizontally movable manner to generate an evenly rotational motion thereof, so as to stably provide an upward force to lift up said body. When one of the blade leafs is pivotally folded by an external force to misalign the blade leafs with each other, the bracket member is kept rotating to generate a centrifugal force to essentially re-situate the blade leafs in line with each other so as to re-gain a control and balance of the body.

Abstract: A motion-detecting note holder is disclosed. Such a note holder includes a note retention member, a motion sensor, a note-waiting indicator, and a controller in communication with the motion sensor and the note-waiting indicator. The controller, upon receiving a motion-detection signal from the motion sensor, causes the note-waiting indicator to provide a human-perceptible indication that a note is in the note retention member.

Abstract: A novel method of manufacturing a novel recording media is disclosed. The manufacturing method includes obtaining a substrate having an inside diameter and an outside diameter and creating a radial profile of an intensive property, such as Hc, of a multilayer magnetic layer containing at least a first magnetic layer and a second magnetic layer deposited on the substrate, from the inside diameter to the outside diameter by forming a radial profile of an extensive property, such as MrT or T, of either the first magnetic layer or the second magnetic layer from the inside diameter to the outside diameter.
