Abstract: In one form, a projection frame eyelid heater includes a heating element and a frame. The heating element has first and second heat producing areas separated by a distance corresponding to a separation of human eyes and has first and second ends. The heating element produces heat in response to an application of a voltage thereto. The frame includes a left temple attachment portion and a right temple attachment portion each having a respective back portion extending downward and inward, a left eyelid chassis portion, an intermediate chassis portion, and a right eyelid chassis portion, wherein the intermediate chassis portion connects the left eyelid chassis portion and the right eyelid chassis portion. Each of the left eyelid chassis portion and the right eyelid chassis portion is adjustable with respect to the intermediate chassis portion in a direction from the user's nose toward the user's left and right eyes, respectively.

Abstract: A method of operating a virtual image generation system comprises allowing an end user to interact with a three-dimensional environment comprising at least one virtual object, presenting a stimulus to the end user in the context of the three-dimensional environment, sensing at least one biometric parameter of the end user in response to the presentation of the stimulus to the end user, generating biometric data for each of the sensed biometric parameter(s), determining if the end user is in at least one specific emotional state based on the biometric data for the each of the sensed biometric parameter(s), and performing an action discernible to the end user to facilitate a current objective at least partially based on if it is determined that the end user is in the specific emotional state(s).

Abstract: Improvements to an engine comprise an air compressor cylinder with a piston, a combustion chamber cylinder with a piston. An engine has added an expansion chamber cylinder with a piston. Pistons each have a connecting rod and connecting rod head and associated parts adapted for reciprocating motion via combustion products, and a transmission associated with the engine. Improvements are to the piston seals, ignition assembly, valve shape and stem/rocker, valve operating mechanism, construction of head, heat management/heat shield, connecting rod/piston rotator, engine balancing, fuel pump placement, and a machining process.

Abstract: A method, apparatus, system, and computer program product for operating air vehicles. Missions for the air vehicles are grouped into categories based on durations of the missions. The missions within the categories are clustered into subsets of the missions that can be concurrently performed to meet a set of mission performance criteria. The subsets of the missions are assigned to a set of air vehicle supervisors.

Abstract: A request is received at a virtual service simulating a particular data service. The request includes a uniform resource locator (URL) that includes a service root portion and a resource path portion identifying a particular resource of a data structure. Syntax of at least the resource path portion is verified based on a particular protocol. Consistency of the resource path portion with a structure of a data model corresponding to the particular data service is also verified. A query of a database is performed based on contents of at least the resource path portion and a simulated response of the particular data service to the request is generated using results of the query.
