20100022157 | HELICOPTER - A helicopter includes a system to effect motion in a horizontal dimension thereby to direct the desired direction. The rotor blades are driven by a rotor shaft and which is hinge mounted on this rotor shaft, such that the angle between the plane of rotation of the main rotor and the rotor shaft may vary. A control for moving the angle of incidence of at least one blade of the rotor cyclically along at least part of a 360-degree rotation path around the rotor shaft. This causes a variation in a lift force of the blade along at least part of the rotations path. This causes the body to be urged in a relatively horizontal direction from a relative position of rest. The control includes an actuator for engaging with an assembly depending from the rotor, the inter-engagement of the actuator and assembly effecting a change in the angle of incidence of at least the one blade of the rotor. The system includes a rotor, preferably complemented with a stabilizer rotor. There is a control ring attached to the main rotor, and an actuator device connected with the helicopter body structure. The control ring is generally centered around the vertical rotor axis, and moves with the rotor when tilted around the feather axis. | 01-28-2010 |
20100130093 | Helicopter with main and auxiliary rotors - A remote control toy helicopter has a main rotor and an auxiliary rotor both driven by a rotor shaft. The auxiliary rotor has elongated elements at an acute angle relative to blades of the main rotor. A control system is provided that includes an actuator for engaging with a control assembly depending from the auxiliary rotor. The inter-engagement of the actuator and the control assembly effects change in the angle of incidence of the elongated elements of the auxiliary rotor. The interaction occurs when the assembly engages with the actuator by a depending arm associated with the assembly. | 05-27-2010 |
20100144234 | STORAGE HOUSING FOR A REMOTE CONTROLLED TOY - A storage housing is provided for stowing a remote control toy. The housing comprises a substantially box shaped body with an interior compartment. The compartment has a platform for movement between two positions, and a door for moving between an open and closed position. There is a remote controller for operating the platform and door in a selected manner and also for operating the remote controlled toy. The housing can additionally be part of a vehicle and have wheels. | 06-10-2010 |

20080243431 | MONITORING SYSTEM - A monitoring system ( | 10-02-2008 |
20090033635 | Instruments, Touch Sensors for Instruments, and Methods or Making the Same - A touch sensor module for an instrument may comprise a touch sensor panel including a plurality of electrodes and a plurality of sensor regions on the touch sensor panel. Each sensor region has an electric field defined by the electrodes and a ground surrounding the electrodes. A processor may be configured to monitor the electric field and to determine that a sensor region of the touch sensor panel is being touched by a user when the electric field associated with that region is altered. | 02-05-2009 |
20090190713 | Monitoring Devices, Monitoring Systems, and Methods of Monitoring - A method of monitoring activities of a user may include receiving information about the user, determining whether the user takes a step, determining the number of steps taken by the user and the length of the steps, and determining at least one of speed of the user, distance traveled by the user, and heart rate of the user. | 07-30-2009 |
20120108086 | BICYCLE METER - A bicycle meter including a rechargeable battery, and a retractable USB plug movable between a retracted position and an extended position. In addition, the USB plug is connectable with a USB port to transfer data between the bicycle meter and a computer and to recharge the rechargeable battery, when the USB plug is in the extended position. | 05-03-2012 |
20140221854 | MEASURING DEVICE, INCLUDING A HEART RATE SENSOR, CONFIGURED TO BE WORN ON THE WRIST OF A USER - According to various aspects of the present disclosure, an Optical Heart Rate Sensor is designed to pick up the heart rate pulse when worn on a user's wrist instead of wearing a bulky chest strap, which is not comfortable. An example optical heart rate sensor unit has two light emitting diodes that provide light source projected to skin. An optical detector mounted close to the light source can detect the movement of blood under the skin of the wrist based on light reflected from the skin. The optical detector can detects blood movement by emitting light onto skin and measuring the amount of light absorbed by skin. The optical sensor can be very sensitive to light, electrical static and electromagnetic waves. A special chamber is designed to protect the sensor unit so that the sensor unit can work when user wears the sensor on the arm. | 08-07-2014 |

20100246871 | Portable Hearing Amplification System and Method - A hearing amplification system. The system has a rechargeable hearing amplifier and a portable charging system. The rechargeable hearing amplifier has a rechargeable battery, a sound amplification portion which will receive sound waves from between 200 to 6000 Hz amplifies sound waves to between 40 dB and 60 dB and broadcast the sound waves to a human user. The rechargeable hearing amplifier also has an ear engaging membrane which is designed to secure to a human ear. The amplification system also has a portable charging system to charge the rechargeable battery in the rechargeable hearing amplifier. The portable charging system has a single 1.5 V battery charger, and alternatively an AC adapter providing 3 V DC. The portable charging system has a seat for charging the rechargeable hearing amplifier and at least one seat for the ear engagement membrane. | 09-30-2010 |
20110085685 | Sound Amp Ear Device with Ear Phone Jack - A sound amplification system which has a sound application ear device operating a programmable control board. The control board provides a low pitched signal and a high pitch signal. It also provides a mono audio signal and a stereo audio signal and a recharging current. The recharging current charges the rechargeable battery. The rechargeable battery provides power to the device. A microphone is also provided and it transmits exterior sound signals to the programmable control board. An earphone operates with the device and can receive the stereo audio signal. The mono audio signal is amplified and broadcast through a first speaker in the ear device. The stereo audio signal is amplified and broadcast through a second speaker in the earphone. | 04-14-2011 |
20110223864 | Ear Tip Method and Apparatus - An ear tip for a sound device. The ear tip has an asymmetrical arrangement which more closely aligns with a user's ear canal. The ear tip includes an ear tip base, ear tip shaft, and a first group of low-profile flanges. The ear tip is arranged along an ear tip central axis. The ear tip has a sound tube connection and a sound channel which extends through the ear tip base and ear tip shaft. The first group of low-profile flanges are spaced along an ear tip shaft axis, and extend radially from the ear tip shaft in perpendicular alignment to the ear tip shaft axis. A first flange, a second flange and an intermediate flange are provided. Each flange is constructed of a flat roof with a downwardly transitioning radial wall. There is a space between each of the flanges. The flanges seal against the ear wall to attenuate sound and reduce resonance. | 09-15-2011 |
