Appl. No.:

12/412709

Assignee:

NORTH AMERICAN LIGHTING, INC. - Farmington Hills MI

International Classification:

B60Q 1/00

US Classification:

362538

Abstract:

A system and method for exterior projection lighting of a vehicle include a generally ellipsoidal faceted reflector disposed on a rear side of a projection lens. First and second focal points of each facet define corresponding reflector focal regions. A semi-conducting light source positioned at an acute angle, such as a single light emitting diode (LED) without a primary optic, emits light toward the reflector from within the first reflector focal region. Reflected light passes through the projection lens to illuminate a desired beam pattern. A curved shade disposed between the projection lens and the light source has at least a portion of a top edge disposed within the second reflector focal region. The shade blocks a portion of reflected light from extending below the optical axis.

International Classification:

H04L 1/00

Abstract:

A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

H04W 72/04
H04W 72/08

Abstract:

An uplink non-orthogonal multiple access for narrowband machine type communication used for the deployment of Internet of Things (IoT) interconnected devices where one or more user equipment are configured for uplink transmission with one or more uplink time-frequency regions for enhanced Machine Type Communication Non-Orthogonal Multiple Access. The configuring is based on defining and signaling one or more signal thresholds and one or more of a resource assignment, a starting subframe periodicity, a starting subframe offset, a time duration in each period, a demodulation reference signal cyclic shift assignment, orthogonal cover code assignment, and interleaver assignment.

International Classification:

H04L 5/00
H04L 1/00
H04B 7/06

Abstract:

Embodiments described herein encode data for multiple-segment transmission in a communication channel by encoding payload bits with an outer code and distributing the outer encoded payload bits to a plurality of N element coders, where N is an integer greater than one. At each of the N element coders the respectively input outer encoded payload bits are encoded with a respective element code. Outputs of the N element coders are encoded with an inner code such that the inner code applied to at least one of the outputs of the N element coders is a function of the output of at least one other of the N element coders. Finally, N discrete inner coded outputs are provided for transmission in respective N discrete segments of a wireless channel. The examples present polar element coders and the inner code combines outputs of certain element coders with an exclusive-OR function.
