| 20080259630 | LENS ASSEMBLY - A lens assembly for use with a light source and including an inner lens and a light directing portion. The inner lens collects light rays from the light source through a light-collecting face and emits at least a portion of the light rays radially through a series of collimators. The light directing portion may be an outer lens having light-collecting faces and light-distributing faces. The light-collecting faces correspond with the collimators and distribute the light rays through light-distributing faces. The light direction portion may alternatively be an outer reflector. The reflector has a plurality of light-reflecting surfaces, corresponding to the collimators, and configured to reflect the light rays emitted from the collimators. | 10-23-2008 |
| 20080304277 | INCREASED EFFICIENCY LED PROJECTOR OPTIC ASSEMBLY - A projector optic assembly for generating and projecting a high gradient beam. The assembly includes a light pipe defining an optical axis and having a collection unit, a funneling unit, and an emitting surface. The collection unit extends from a first end to a transition plane defining the transition from the collection unit to the funneling unit. The collection unit is configured to collect light from a source and direct it through the transition plane, whereafter the funneling unit extends from the transition plane to the emitting surface. The emitting surface has an area smaller than an area of the transition plane selected to increase the efficiency of the funneling unit. Spaced apart from and generally opposite of the emitting surface is a condenser lens | 12-11-2008 |

| 20090080413 | IP Telephone System - An Internet Protocol (IP) telephone has a constant impedance filter that is capable of being continuously attached to the physical layer of a computer chip in the IP telephone. The constant impedance filter is located outside the physical layer and is connected to a relay on the physical layer. The relay is configured using native FET devices, which are normally conductive without a supply voltage. Therefore, the relay is capable of operating during the discovery mode of IP telephone operation, where no power is applied to the substrate. Rectifier circuits rectify an incoming signal during discovery mode, and apply the rectified signal to the gate of the relay to improve conductivity of the relay. This allows for faster detection of the IP telephone during discovery mode. During normal operation mode, voltage is applied to the physical layer, and the relay is opened by grounding the native devices. Also, during the normal operation mode, any signal coming from the constant impedance filter is terminated in a switchable termination resistor that is also disposed on the physical layer. | 03-26-2009 |
| 20100067521 | Internet protocol telephone system - An internet protocol telephone includes a substrate having an input and an output that are capable of being connected to the internet protocol (IP) network. A relay is disposed on the substrate and is connected between the input and the output of the substrate. The relay includes first and second native FETs that have a threshold voltage of approximately zero volts. Therefore, the relay is nominally turned-on, even when little or no voltage (or power) is applied to the IP telephone substrate, as during the discovery mode of IP telephone operation. During discovery mode, The IP phone is configured to be responsive to extended link pulses and block data packets that are associated with legacy devices. Data packets have a higher signal duration and are more continuous than extended link pulses. The IP phone includes a switchable ground that is connected to the gates of the native devices, and is controlled by a rectifier and filter circuit that are connected to the substrate input. If the IP phone receives legacy data packets during discovery mode, then the high signal duration and continuous nature of the data packets are sufficient to cause the rectifier to generate a rectified signal having sufficient amplitude to activate the switchable ground, so as to ground the gates of the native devices and therefore turn-off the native devices. Therefore, the data packets are rejected and are not passed back to the switch. Extended link pulses have a frequency that is too low to generate a rectified signal that is sufficient to activate the switchable ground, and therefore the native devices remain turned-on. Accordingly, the extended link pulses are passed back to the switch. | 03-18-2010 |
