A control module located within the traffic signal, the control module comprising a controller for implementing a primary loop that continuously checks environmental conditions via the sensor to determine if a predetermined condition is met.

Abstract: A system comprising an illumination system to direct light from one or more light sources to a limiting output pupil of a projection optomechanical system, a liquid crystal on silicon display panel (LCOS) to modulate the light from the projection optomechanical system and to direct the modulated light back toward the projection optomechanical system, and an in-coupler to a combiner waveguide to receive the modulated light from the LCOS, after it passes through the projection optomechanical system. The system in one embodiment is designed so that the light that passes through the projection optomechanical system from the illumination system lands on the LCOS within the limiting output pupil of the projection optomechanical system.

Abstract: MIMO dual-polarised antenna assembly arranged in a nested arrangement. The antenna assembly comprises a ground plane and a dual-polarised lower band antenna elements mounted to the ground plane proximal to peripheral sides of the ground plane. The location of the lower band antenna elements defines a lower band peripheral boundary. The antenna assembly comprises (1) dual-polarised upper band antenna elements mounted to the ground plane, nested within the lower band peripheral boundary, (2) an upper feeding network configured to connect opposing pairs of lower band radiating elements of the dual polarised lower band antenna elements and feed the lower band antenna elements, the upper feeding network being located within the lower band peripheral boundary, and (3) a lower feeding network positioned below the upper feeding network, and is configured to feed the dual polarised lower band antenna elements via the upper feeding network using a pair of ultra-wideband duplexers.

Abstract: A method of forming a composite component from a plurality of feed materials by the application of heat is disclosed. A negative mould (102) is obtained defining the geometry of the component to be formed. First feed material (104) and second feed material (104) are deployed into the mould. The temperature is increased during a heating stage to a first temperature above the melting point of a feed material, so as to cause the powdered feed material to melt within the mould. The temperature of the mould is decreased during a cooling stage to consolidate the feed materials forming a solid component.

Abstract: The forming of the metal component is disclosed, in which feed material is initially in a powdered state. A sacrificial positive model (102) of a component is created and a negative mould (104) is built around said positive model from a material having a melting point higher than the melting point of the metal from which the component is to be formed. The sacrificial positive model is removed from the negative mould. Feed material (108) of metal powder is deployed into the mould and the metal powder is heated to a temperature higher than the melting point of the metal powder, so as to cause the metal powder to melt within the mould.

Abstract: An improved hitch adapter allows an individual to attach a vehicle with a hook to a trailer with a ball coupler. The improved hitch adapter comprises an adapter ring mechanically coupled to a front plate. The front plate is mechanically coupled to a first parallel surface. The first parallel surface further comprises an adapter ball inset. The first parallel surface is mechanically coupled to a left plate and a right plate. The adapter ball inset is mechanically coupled to a height-adjustable ball. The right plate and the left plate are mechanically coupled to a size variable clamp. This enables a user to mechanically couple the hook to ball coupler regardless of size of the ball coupler enabling full articulation in a vertical direction and a rotational direction.

Abstract: Systems, methods, and lottery tickets provide lottery games with gameplay that allows a variety of play options and results a rich prize structure. Gameplay can be centered on a lottery game player or a related entity, which can comprise other lottery game players. Gameplay centered on the lottery game player can be customized to a specific segment associated therewith. Play options can include iterative gameplay and gameplay reliant on information supplied by the game player. Features of the rich prize structure include monetary prizes that can include cash awards and non-cash awards. Monetary prizes can be awarded in response to active game play or passive gameplay. Other monetary prizes can be redeemed during a period of time and can include award terms that benefit the lottery game player or the related entity (relative(s) of the lottery game player, non-profit organization(s), prize supplier(s), etc.).
