Abstract:
Systems and methods are described that provide a phantom mobile telephone number that is assigned by the mobile telephone service provider, for business customers and/or customers subscribing to the service. Upon receipt of the phantom mobile telephone number at the mobile service provider's internal call routing system, the call is associated with a preexisting landline number assigned to a business. The mobile telephone call is forwarded to the preexisting landline telephone number and is not charged airtime minutes.
Abstract:
An electrical connector assembly or cable assembly that carries a combination of radio frequency signals, high speed digital communication signals, and direct current DC power signals is disclosed. The electrical connector assembly exhibits environmental protection. Other features include providing blind mate connection that may be used in a radio transport or fiber transport repeater system for a wireless network.
Abstract:
A starter stopper for use with a high intensity discharge (HID) lighting source includes a timer and switch. The timer controls the durations of on-time and off-time periods during an energizing period. The starter stopper connects the HID lighting source to power to start the HID lighting source during on-time periods, and disconnects the HID lighting source from the power to start the HID lighting source during off-time periods. A method of starting and stopping an HID lighting source includes initiating an energizing period in response to application of power to a starter stopper, enabling the HID lighting source to be connected to power to start the HID lighting source during on-time periods by the starter stopper, enabling the HID lighting source to be disconnected from the power to start the HID lighting source during off-time periods by the starter stopper, and stopping the energizing period in response to removal of the power to the starter stopper.
Abstract:
A compact luminaire which includes a housing, a ballast, and a first and second electrical component. The housing has a back and a perimeter wall which extends generally perpendicularly from the back. The perimeter wall has a top wall portion, a bottom wall portion disposed in a downward direction with respect to the top wall portion and sidewall portions connecting the top wall portion and the bottom wall portion. The ballast is mounted to the back adjacent the bottom wall portion and is substantially equidistant to the side wall portions and the first and second electrical components are mounted to the housing on opposite sides of the ballast in a balanced fashion.
Abstract:
A receptacle assembly for a twist-lock photocontrol that is mounted on a luminaire housing. The assembly includes a receptacle and a spring clamp. The receptacle has a disc portion with a hub extending from the central portion of the back side, a perimeter side wall with a castellated bottom edge that engages stops on the luminaire housing. Three fingers extend from the back side of the disc and terminate at a lip edge. The spring clamp has a substantially flat, ring-shaped body that includes a top surface, an opening, an inner edge, an outer edge, and at least one pair of spring members. The receptacle is attached to a luminaire housing using the spring clamp. The orientation of the receptacle can be adjusted and can be locked into a stationary position without tools.
Abstract:
It has been determined that certain dual-chambered cardiac stimulators may operate in a region in which an atrial pacing event may obscure the detection of a ventricular tachyarrhythmia. Various exemplary techniques may be used to improve the ability of dual-chamber cardiac stimulators to detect such ventricular events. In accordance with one technique, it is determined whether a ventricular event should be classified as a ventricular tachyarrhythmia. If not, the VA interval is restarted as usual. However, if the ventricular event may be classified as a ventricular tachyarrhythmia, it is determined whether the ventricular event falls within the region in which an atrial pacing event may obscure its detection. If not, then the VA interval is restarted as usual. However, if the ventricular event falls within this region, the VA interval is restarted with the VT rate detection boundary. This has the effect of lengthening the VA interval and the AA interval in this region so that atrial pacing events will not obscure the sensing and treatment of ventricular tachyarrhythmias in the region.

Abstract:
It has been determined that certain cardiac stimulators may operate in a manner in which the ventricular pace refractory period (VPRP) may be greater than the post-ventricular atrial refractory period (PVARP). Various exemplary techniques may be used to improve the ability of cardiac stimulators to lengthen the PVARP. In accordance with one technique, the VPRP is adjusted with the pacing rate so that as the pacing rate becomes slower the VPRP increases. The VPRP is compared with the PVARP. The PVARP remains constant until the VPRP becomes greater than the PVARP. Then, the PVARP is adjusted to make it greater than or equal to the VPRP. In accordance with another technique, the VPRP and the PVARP are adjusted with the pacing rate, with the PVARP remaining greater than or equal to the VPRP.
Abstract:
A scheduling grid is provided for displaying summary availability information for a group of users in a collaborative environment. The system may enable users to share calendars with other users within the collaborative environment so that a meeting organizer can schedule a meeting at a time when all or most of the users are available. The system may collect availability information from the users' individual calendars and may aggregate the availability information in a master calendar, which may display the aggregated availability information for the group of users in a scheduling grid. Scheduling grid timeslots may display the aggregate availability information for the group of users and may graphically indicate when all users are available and when one or more users are unavailable during a timeslot. The aggregate availability information may enable the meeting organizer to quickly determine an available time for scheduling a meeting.
