摘要:
An optical disk drive includes a spindle motor to turn an optical disk and an OPU configured to apply an image to a coating within a label region of the optical disk. An encoder is configured for tracking disk speed features on the optical disk in a region distinct from the label region defined on the disk. By tracking the disk speed features, the encoder obtains disk speed data for use in applying the image to the label region.
摘要:
An optical disk includes a label region having writable material. Disk speed features are located in a manner which allows them to be readable when writing to the label region.
摘要:
A motor hub is disclosed. The motor hub comprises a housing for a motor. The housing is rotatable around an axis of rotation of the motor. The motor hub also has marks arranged on a surface of the housing, and spaces between the marks. The marks and spaces form a pattern readable for sensing a rotational speed of the motor.
摘要:
A reflector for a projector includes a metal reflector that defines an optical surface. An absorptive surface is disposed on the optical surface. A band-pass reflective surface is further disposed on the absorptive surface.
摘要:
A lamp—suitable for use within a projector or other high-light output application—includes an ultra high pressure bulb. An extension from the bulb defines a start-up bubble. A conductor is carried by the extension of the ultra high pressure bulb, generally enclosing the start-up bubble, thereby exciting gas contained within the start-up bubble. A header defines a socket within which the extension and the conductor are carried.

An integral reflector and heat sink for use in a projector assembly includes a reflector portion comprising an integrated heat sink and a plurality of integral cooling fins connected to the integrated heat sink.
摘要:
A reflector includes a hyperbolic surface for reflecting light, a focal point, an opening for insertion of a light source having an origin of light emission, and a datum structure for orienting the origin of light emission to the focal point.
摘要:
A replaceable lamp assembly includes a lamp coupled to a lamp header; and a cap coupled to the lamp header that at least partially covers the lamp. The cap minimizes contamination of the lamp and is configured to allow selective exposure of the lamp.
摘要:
A method of forming a lamp assembly includes establishing a temperature difference between an anode and a reflector. The anode has a dimension larger than an opening defined in the reflector when the anode and the reflector are at the same temperature. The method also includes moving the anode to an aligned position at least partially within the opening and reducing the temperature difference.
摘要:
A light source module includes a lamp assembly having an integrated reflector and heat sink, the lamp assembly having a pressurized gas contained therein, an anode sealingly coupled to the integrated reflector and heat sink, and a cathode sealingly coupled to the integrated reflector and heat sink; and a projector protection system including at least one first projection feature for suspending current flow from the cathode to the anode when at least one first threshold is exceeded and at least one second projector protection feature for stopping the current flow when at least one second threshold is exceeded.
