With small dimensional optics, small photovoltaic cells have heat distribution surfaces, very high concentrations and subsequently high utilization of the semiconductors can be achieved. Discrete photodiodes can be formed as spherical and other geometric shaped, cells with high performance characteristics, precision dimensions, and low cost. This invention positions discrete photovoltaic cells by using their geometric shape, elastic electrical mounts, couples them to small optical concentrator systems of refractory and or reflective optics and makes electrical network connections to those photodiodes, reliably, adjusting for thermal expansion, and at low cost to form low cost and reliable electrical power arrays. The electrical connectors and network can form part of the reflective optics and heat removal system. The electrical interconnection system can also form a reliable network that is self-correcting and tolerant of point failures.

A communications system connects one or more BTS hotels with several remote access nodes on a transmission ring. Each operator has one or more separate optical wavelengths. Signal flow around the ring can either be uni-directional or bi-directional. Each optical wavelength (or wavelength pair) contains the wireless signal traffic for all remote nodes in the ring for the operator using that particular wavelength in digital form. At each node, the incoming signals are electrically demultiplexed and appropriate signals for that node are extracted for conversion to RF. These signals are copied rather than cut so that they are also available at following remote antenna nodes, thereby enabling simulcast operation.

A sleep circuit for use in a resonant inverter is disclosed. The sleep circuit activates a “sleep mode” (non-continuous operation) when the inverter output has no connected load, or a connected load is non-operative (e.g., fails). The “sleep mode” utilizes hysteresis control via the under voltage lockout protection feature of a control IC of the inverter. A primary DC source permanently connects to the Vcc pin of the control IC for startup (on) and burst (non-continuous) operation modes. An auxiliary DC source connects to the Vcc pin via a switch for continuous operation mode. A load current sensor controls the switch. When a sensed output current is above a threshold level, the switch connects the auxiliary DC source, and the control IC (and the inverter) operates continuously. When the sensed output current falls below the threshold, the auxiliary DC source is not provided and the inverter operates in “sleep mode”.

In a monitoring device and system, a monitoring data inserter inserts monitoring data of a predetermined pattern into an idle period of input data to be transmitted to a transmission line. A monitoring data checker having received the monitoring data through the transmission line, when determining that the monitoring data does not maintain the predetermined pattern, provides selective switchover instructions to a selector to be controlled. Then, the monitoring data checker sequentially performs a selective switchover to processors, thereby detecting a failure point in the processors. Also, when the failure point in the processors can not be detected, the monitoring data checker provides channel switchover instructions to a switching portion and performs a channel switchover of the transmission line, thereby detecting which channel of the transmission line has caused a failure.
