20120185723 | EFTB UNIT, USB DEVICE WITH THE EFTB UNIT AND METHOD FOR RESETTING AND REENUMERATING THE USB DEVICE - A method for resetting and reenumerating a Universal Serial Bus (USB) device, an Electrical Fast Transient/Burst (EFTB) unit of a USB device for resetting and reenumerating the USB device and a USB device are described. In one embodiment, a method for resetting and reenumerating a USB device involves detecting a USB reset command from a host device at a USB device, setting a reset flag in the USB device in response to the detecting of the USB reset command, determining if the USB device is in a corrupted state in response to the reset flag, and causing a Single Ended Zero (SE0) signal to be issued to reset the USB device out of the corrupted state and reenumerate the USB device back to the host device if the USB device is determined to be in the corrupted state. Other embodiments are also described. | 07-19-2012 |
20100271839 | LIGHT GUIDE DISPLAY WITH MULITPLE LIGHT GUIDE LAYERS - A light guide display includes a printed overlay layer, a first light guide layer, and a second light guide layer. The printed overlay layer includes an input region with a symbol that is at least partially translucent. The first light guide layer is disposed on a back side of the printed overlay layer to illuminate the symbol of the printed overlay layer in response to illumination of the first light guide layer. The second light guide layer is disposed on a front side of the printed overlay layer, opposite the first light guide layer. The second light guide layer includes a separate symbol that is distinct from the symbol of the printed overlay layer. The second light guide layer illuminates the separate symbol of the second light guide layer in response to illumination of the second light guide layer. | 10-28-2010 |
20100264437 | PLCC Package With A Reflector Cup Surrounded By An Encapsulant - In an embodiment, the invention provides a PLCC package comprising first and second lead frames, a plastic structural body, a light source, an encapsulant, and an optical lens. The first lead frame comprises two tongues and a reflector cup. The first and second lead frames are attached to the plastic structural body. The light source is mounted and electrically connected at the bottom of the inside of the reflector cup. The light source is also electrically connected to the second lead frame by a wire bond. The reflector cup is surrounded on at least four sides by the encapsulant, the encapsulant having a domed portion that functions as the optical lens, the encapsulant being an integral single piece structure. | 10-21-2010 |
20100127629 | LIGHT EMITTING DEVICE - A light emitting device is disclosed herein. An embodiment of the light emitting device comprises a first plurality of light emitters comprising a first group and a second group, wherein the first group is connectable in series to the second group. A first driver is connected to the first group. A second driver is connectable to the second group. A first voltage comparator is coupled to the first driver, wherein the voltage comparator compares the voltage of the first driver to a predetermined voltage. The light emitting device is in a first state when the voltage of the first driver is below the predetermined voltage. The light emitting device is in a second state when the voltage of the first driver is greater than the predetermined voltage. The light emitting device is in the first state, the first group is connected in series with the second group to form a series circuit between the first driver and a reference voltage. When the light emitting device is in the second state, the first group is connected between the first driver and the reference voltage and the second group is connected between the second driver and the reference voltage. | 05-27-2010 |
