摘要:
The present invention provides a method for mitigating an unintended-mechanical strain in a device (100). The method includes transducing (304) strain-energy in the device to electrical-potential energy. This strain-energy develops due to unintended-mechanical strain. The unintended-mechanical strain is generated due to an impact force received by the device. Further, the method includes dissipating (306) the electrical-potential energy. The electrical-potential energy is dissipated via an electrical-circuit (204) in the device.
摘要:
An electric motor (100) for controlling the lateral displacement of a shaft (114) connected to a rotor (104) of the electric motor (100) is provided. The electric motor (100) includes one or more stator conductors (106) for carrying a current and one or more permanent magnets (108) to produce a magnetic field (504). The one or more stator conductors (106) interact with the magnetic field (504) when the power is applied, to purposely generate a force with an axial (Fa) and a circumferential component (Fc). The electric motor (100) includes the shaft (114) that travels along a rotor axis (506) in an axial direction when the power is applied, under an action of the axial component of the force. However, when the power is removed, the shaft (114) retracts under the action of a biasing force from a tension device (118).
摘要:
A vibrator assembly (108) comprising a shaft (112) that is connected to a motor (110), to produce vibration in a communication device (500), is disclosed. The shaft (112) includes a track that defines a path with a first component that travels circumferentially around the shaft (112), and a second component that travels along the length of the shaft (112). The shaft (112) rotates due to a rotational force that is generated when the motor (110) is activated. The unbalanced mass (114) travels along the track towards an end of the path proximate a free-end of the shaft (112) when the motor (110) is activated, and retracts due to a biasing force from a tension device (212) when the motor (110) is deactivated.
摘要:
An optical communication system is provided for conveying signals between multiple housing elements of a device, where respective optical detectors and optical light sources interact via a light guide associated with each communication path, where an optical signal produced by the optical light source and received by the optical detector travels a path where at least a first light redirection unit redirects the optical signal between an angle in which the optical signal travels along at least a portion of the length of the light guide, and an angle which allows the optical signal to exit the light guide. In at least some instances, the multiple housing elements correspond to at least a pair of housing elements that are incorporated as part of a communication device having a slider configuration. In some of the same or still further instances, one or more of the light redirection units are diffractive optical elements. In some instances, one or more of the light redirection units are reflectors.
