A technique to manufacture small joint orthopedic implants includes the steps of taking standard radiographs of a pathologic joint and the corresponding non-pathologic joint. In order to provide an accurate frame of reference, a specialized marker is placed in the radiographic field. By inspection of the radiographs and by comparison with the marker, the dimensions of the cortical bone and the cancellous bone can be quickly and accurately determined. These dimensions can be used to manufacture a suitable implant and installation tool. Typically, the implant will include a stem from which a post projects. A radially extending collar is located at the intersection between the stem and the post. A mating head is attached to the post. The head closely approximates the size and shape of the natural head being replaced. The stem will be non-round in cross-section to prevent rotation of the stem in the bone. For many applications, the head will not be fixedly attached to the post, but will be rotatable about the longitudinal axis of the post. One or more spacers that fit about the stem also can be provided in order to adjust the distance that the head projects from the bone.

According to the present invention, a compiler generates, as debugging information on variables appearing in a source program and the allocation of hardware resources, location information made up of elements showing, for each entry of a variable, an address range within which the variable is valid, a condition flag which is made true within the address range when the variable is valid, and a resource allocated to the variable. A debugging device analyzes the debugging information and stores it. When examining the value of a variable, an entry for the valid variable is determined from the address currently being executed and the value held in the condition flag register, and the resource allocated to that variable is obtained. In this way, the contents of the variable can be referenced correctly.

Broadband integrated services are performed via digital, channelized or optically coded networks by a system which organizes, interfaces, provisions, loads and controls, in real time, the transport of grouped or organized information (such as packetized cell data) through interface access devices and packet switches that are compliant with domestic and international communication standards. A packet core network includes multiple packet switches and interface access devices coupled to an existing narrowband or broadband network. A signaling manager, a provisioning manager and a traffic manager perform all broadband and narrowband routing, port provisioning and connecting functions for all network devices. A set of software interface modules for each equipment vendor allows the provisioning manager, the signaling manager and the traffic manager to impose control demands and make network management decisions on a real time basis via an application protocol interface. Bit error rate caused by the disparity between low speed (such as TDM) networks and high speed (such as OCR) networks is substantially reduced by synchronizing the overall network and all switching components to a primary reference clock that has an accuracy of 1×10⁻¹¹ second per month or better.

A video projection calibration technique includes a first camera to view the video display screen from the projector side, and a second camera to view the video display screen from the viewing side. The first camera may be a lower resolution than the second camera. The combination of the two cameras permits the transfer functions of the projection system and the first camera to be characterized and reduced to a warping transform that may be stored by the control system. The presence of the warping transform would permit the lower resolution, first camera to perform image realignment after the video projection system is in use by an end user.

The post member extends along a longitudinal axis and the pivot mechanism allows the post member to be moved about two, substantially perpendicular pivotal axes relative to the tripod to align the longitudinal axis of the post member with the vertical. Once the axis of the post member is aligned vertically, the alignment system of the attachable satellite dish will then have a proper reference from which to aim or direct the dish (e.g., azimuth and elevation) for best reception and transmission. The mount includes an arrangement of cables extending between the tripod legs and adjustable straps extending between each tripod leg and the post member to provide a very strong and stable support for the satellite dish antenna system that is attachable to the upper end of the vertically aligned post member. The tripod is designed to be foldable into a compact configuration for easy transport and storage with each tripod leg folded onto itself and positioned under a central member of the tripod. The folding and unfolding of the tripod and the alignment of the post member to the vertical on it can all be done by one person without the need for any tools.
