Abstract: A system for pricing and reserving charter vehicle services includes a central database, first and second real-time databases, and a controller. The central database receives and stores itinerary data. The controller searches the first real-time database to identify at least one route between the departure and destination locations and the second real-time database to determine whether a charter vehicle is capable of being operated on the routes. The controller further determines availability of the charter vehicle and the routes and determines feasibility of operating the charter vehicle on the routes, generates travel schedules, provides prices for travel schedules, receives payment for one of the travel schedules, and reserves the travel schedule.

Abstract: Systems and methods for biasing an externally modulated laser. An inductorless bias T network is provided that includes a terminating resistor in series with a capacitor. The capacitor is an open circuit for a bias signal and a virtual ground for an RF signal. Thus, the RF signal is terminated by the terminating resistor without dissipating the bias signal through a ground return path of the RF signal. Using a charge pump inverter, a positive supply can be used to positively bias a laser and negatively bias the external modulator through the terminating resistor. A negative power supply is not required. A swing voltage provided by the RF signal causes the external modulator to modulate the light emitted by the laser.

Abstract: A transceiver module is provided that includes an optical subassembly having an extension with traces corresponding to traces defined on an associated transceiver substrate. A connector element including a flexible, non-electrically conductive substrate within which is disposed an array of conductors is placed between overlapping portions of the extension and the transceiver substrate so that upper ends of some of the conductors contact the traces of the extension, while lower ends of those same conductors contact the corresponding traces of the transceiver substrate. In this way, the connector element provides electrical communication between the optical subassembly and transceiver substrate, while also accommodating misalignment that may be present, or develop, in the transceiver module components.
