Specifically, the optical transmission module includes Peltier elements disposed inside a metal case, a metal base disposed upon the Peltier elements, a laser diode substrate disposed upon the metal base, a laser diode disposed upon the laser diode substrate, a thermistor substrate disposed upon the metal base, a thermistor disposed upon the thermistor substrate, and a thermally conductive member, disposed in the vicinity of the thermistor, that has a height greater than the height of the thermistor.

Abstract: A method for automatically updating firmware of a hand-held device. To initiate the automatic update, a reset of the hand-held device is detected and an update application is executed. The update application determines whether a flag, indicating a pervious execution of the update application, has been set. If the flag is set, the update application terminates, otherwise, the update application performs an identification test by determining whether a device ID of the device matches a device ID stored in a table of the update application. If the device ID does not match, the update application terminates and the flag is set. If the device ID matches, the update application updates the firmware of the hand-held device, sets the flag, and terminates. In so doing, the firmware of the hand-held device is updated without requiring user intervention or interaction.

Abstract: Function calls for a program are sampled to determine call counts in the program. The call counts are determined based on sampled function calls collected during sampling intervals.

Abstract: A method of providing a software patch to an electronic device. A device containing a software patch for an electronic device may be plugged to an electrical outlet. A plurality of electronic devices may be queried, over a power line through the electrical outlet, for identifying the electronic device requiring the software patch. As a result, the electronic device requiring the software patch may also identify the version of the firmware installed on the electronic device. Test signals may be sent over the power line to determine the signal quality of various multiple carriers for using OFDM scheme. Suitability of various sub-carriers for sending the software patch over the power line may be determined. Higher density modulation may be used for higher quality sub-carriers to send the software patch to the electronic device. An acknowledgment signal for receipt of the properly received authenticated software patch may be received.

Abstract: A closed loop system for controlling laser temperature without the need for additional sensors or other hardware. Embodiments utilize an existing automatic power feedback loop and existing sensors to determine the temperature of a TOSA based on changes in laser bias current, thus avoiding the need for the additional hardware. The automatic power feedback loop will modify the laser bias current as the temperature of the TOSA changes. That is, as the temperature increases, the amount of laser bias current is increased and as the temperature decreases, the amount of laser bias current is decreased. Thus, the laser bias current may be used as feedback for the laser temperature control. Accordingly, when the transceiver module drops below a predetermined temperature, a laser heater current may be controlled to thereby maintain the same laser bias current as at the preset temperature.

Abstract: A tool for classifying and installing patches on terminals. Specifically, when a patch is designed, it may be automatically installed on a terminal if it does not have a direct impact on the terminal and is not in an area which relevant to the terminal user.

Abstract: A method for software change modeling for network devices provides dynamic (on the device) and static (computer) change modeling. The same source code and libraries are used for both modeling applications, allowing a user to see the impact of activating or deactivating specific software modules without affecting the actual node. A master node passes a node the identity of the software package(s) to be updated and the dependencies. The node notifies its running processes about the update. If any of the processes determine that the update will degrade or have a negative impact on the operation of the node, it returns a veto to the node which sends a list of the processes that are impacted along with the reasons why to the master node.

Abstract: Graphical display support is provided within a process plant configuration, monitoring and simulation system to enable graphical displays to be created in a manner in which they are associated with one another in the runtime environment. In particular, a single graphic display editor may be used to create interrelated graphic displays that may be accessed from one another in the runtime environment to provide further information about a process entity within one of the graphic displays, to scroll through adjacent sections of a process plant or to provide different displays for different functions within the process plant, such as for an operator viewing function, a simulation function and a maintenance function. Because the same graphic editor is used to create the graphic displays, the resultant graphic displays may have the same look and feel and may be bound to the runtime environment within the plant in generally the same manner.

Abstract: A method and device implementing a downloadable operatively connected to a plurality of gaming machines either by a direct communications link or through the use of one or more site controllers or PCs. Each gaming machine and site controller or PC contains two executable spaces, one of which typically contains the software image currently being implemented by the device. The other executable space is designated to receive from the central system a new software image that will be utilized by the device. The central system transfers a new image to be executed, via packet encrypted communications, to a networked device which stores the image in an executable space, while continuing to run the currently designated image. Upon instruction from the central system, the device switches over to the new image, allowing one or more machines to implement a software upgrade on a continuous basis.

Abstract: A mechanism for the rapid prototyping of code whereby a user selects a subsection of code and runs multiple evaluations on the selected code and altered versions of the code without first saving and naming the code subsection is disclosed. The selected subsection of code, referred to as a code cell, groups multiple lines of code together and evaluates them together. Output from the analysis is displayed to a user. Algorithms may be altered and variable values may be modified in-place as required to achieve an optimal result for the user. Once a desired version of the code is established, the code may be saved and then published in multiple user-selected formats with a single command. Each code cell in the program code may be used to generate a separate publication thus creating a narrative effect when sequentially viewing a grouping of the publications in the user-selected format.

Abstract: An RPM subsystem can be installed on a system that has its own native packaging subsystem. The RPM subsystem is initially delivered as a package wrapped in the non-RPM format of the native packaging system and installed. When an RPM package is installed, the RPM subsystem is also configured to create a stub entry in the native packaging, non-RPM system. The stub entry may contain the normal package information, such as name, version, description, as well as a list of files contained in a package. The stub may also contain uninstallation logic, which serves as a “callback” into the RPM subsystem during package removal and causes the RPM subsystem to remove the package when invoked. Removal of a RPM package via RPM tools also causes the removal of the stub entry.
