    • Pathway and landscape lights, in particular to devices, apparatus, systems and methods of using ground directed pathway and landscape lights with a single or perimeter spaced apart LED (light emitting diode) light sources on a disc mount, with or without an optical fiber arranged in a ring pattern about a perimeter edge of the mount. A light shade lens can have an upper end attached to the lower face of the disc mount, and a bottom end attached to a ground engaging post, so the light emitted from the mount is directed in a 360 degree outwardly expanding direction expanding outward on the ground surface where the ground engaging post is in the center of the 360 degree expanding illumination. A low voltage power source can be used. Alternatively, the light can be solar powered. The light forms uniform light beam emissions without shadow spots effects.

    • A fluid actuator with fluid limit valves (550, 551) and optional adjustable mechanical limits enables the construction of fluid linkages which are able to completely replace mechanical linkages. In a fluid circuit comprising of two or more fluid actuators, the pistons (102) of the fluid actuators can become uncorrelated when fluid leakage occurs. At the piston (102) extension and retraction limits, fluid limit valves (550, 551) open. The open fluid limit valves (550, 551) allow fluid to bypass pistons (102) and/or allow fluid from an external source to compensate the fluid leakage. The fluid bypassing pistons (102) at their extension or retraction limit and/or externally supplied fluid forces the uncorrelated pistons (102) to reach their extension or retraction limit as well. The fluid actuator with optional adjustable mechanical limits have one or more additional pistons (686, 688), which have an adjustable separation from the main piston (102) or end of cylinder. The fluid actuator with fluid limit valves (550, 551) and optional adjustable mechanical limits enables mechanical linkages to be replaced by fluid circuits composed of the fluid actuators.

    • In a telecommunications system (100), a method and apparatus for buffering the initial speech of an initial speaker in a push-to-talk call is disclosed. The method includes the steps of determining at least one participant or group to call (410, 510), sending a call request to the at least one participant or group (520), determining if the at least one participant or group is registered with the telecommunications system, notifying the initial speaker to begin speaking after determining at least one participant is registered with the telecommunications system but prior to connecting all called parties, receiving and digitizing voice packets from the initial speaker, storing the digitized data packets in a storage medium and transmitting the digitized voice packets when a predetermined packet transmission triggering event occurs. The apparatus for buffering the initial speech burst of an initial speaker in a call includes a first server (140) and a second server (150) communicatively connected to the first server. The second server is programmed to execute the steps of the method described above.
