摘要:
An article handling apparatus for gripping and moving an article such as a large tire or other vehicular component of a mining, earthmoving or like vehicle. The article handling apparatus includes a base frame for movement of the apparatus over a substrate surface, and a handling frame for gripping the article, such as a tire. The apparatus has a pair of moveable arm members on the base frame, and a pair of moveable arm members on the handling frame. The apparatus can be compactly stored by contraction of the arms, can be manipulated through tight spaces, and is extremely stable while handling large and heavy articles.

Techniques to schedule activities. In one method, a request to book an appointment for an activity in a particular schedule is initially received. In response, time slots available in the schedule for booking the activity are determined, and a set (all or a subset) of the time slots is provided as possible appointment choices. The time slots in the set are temporarily locked. A next set of time slots or more time slots may be requested (if the time slots provided are not acceptable or desirable), in which case additional time slots may be provided. Thereafter, a selection for one of the time slots is received. In response, the activity is booked in the selected time slot and previously locked time slots are released. The locked time slots may also be released if no selection is received after a particular amount of time.
摘要:
A method, system and apparatus for performing selective data processing based upon a static analysis of the code of a compiled object. A compiled object, for example an enterprise bean, can be analyzed to determine how individual methods in the enterprise bean access specific objects. Those specific objects can include, for instance, data members of a class, or class objects passed into one or more individual methods of the enterprise bean. Where the individual methods of the enterprise bean do not mutate or otherwise change the state of the specific objects, those objects can be accessed by reference only. Importantly, where the specific objects are data fields linked to a table in a database as managed by a container managed persistence (CMP) bean, an update to the table will not be required when the static analysis of the enterprise bean otherwise indicates that the data fields are merely accessed, but not updated.

A method for calling a software method in a called CORBA application by a caller software method in a caller CORBA application in a process of a computer system is disclosed. The caller software method calls a software method in a CORBA stub sending a parameter which is created using a classloader of the caller application. The CORBA stub software method calls a software method in a dynamic proxy sending the parameter. The dynamic proxy software method calls an ORB sending the parameter. The ORB serializes the parameter and returns it to the dynamic proxy software method. The dynamic proxy software method calls the ORB sending the serialized parameter. The ORB deserializes the serialized parameter using a classloader of the called application and returns it to the dynamic proxy software method. The dynamic proxy software method calls the called software method sending the deserialized parameter. Alternatively, instead of the ORB serializing and deserializing the parameter object, the ORB creates a copy of the parameter object using the classloader of the called application.
摘要:
An access device for providing access between a lower substrate surface and an upper substrate surface. The access device includes upper and lower articulated ladder members. A first end of the upper member is pivotally connected to or near the upper surface. A second end of the lower member is pivotally connected to the second end of the upper member, such that the lower ladder member is rotatable 180° relative to the upper member. In the storage position, the ladder members are folded in a substantially compact upright disposition, while, in the access position, the members are aligned and extend downwardly and outwardly.

A gate opening and closing assembly includes a mount that is coupled to a vertical member of a gate that is extendable across an entry way. A drive unit is coupled to the mount and the drive unit is actuated to rotate in a first direction or a second direction. A wheel is rotatably coupled to the drive unit to roll along the ground. The wheel is rotated in an opening direction when the drive unit rotates in the first direction to urge the gate into an open position thereby facilitating a vehicle to drive through the entry way. The wheel is rotated in a closing direction when the drive unit rotates in the second direction to urge the gate into a closed position thereby inhibiting the vehicle from driving through the entry way. A remote control is in wireless electrical communication with the drive unit. The remote control turns the drive unit on and off to open and close the gate.

Techniques to facilitate assignment and scheduling of activities. In accordance with a method, a chart showing a calendar of schedule for a number of available resources is provided in a first frame (or window) in a user interface menu, and a number of objects representative of a number of unplanned activities are provided in a second frame. A selection for an unplanned activity in the second frame (or a planned activity in the first frame) is received and, in response, selected ones of a number of objects in the chart are highlighted based on the selected activity. A request to assign the selected activity to a selected resource and to schedule the selected activity for a particular time duration is thereafter received. The requested assignment and scheduling may be accepted or rejected based on the requirements of the selected activity and the capabilities of the selected resource.
摘要:
A method and apparatus for subclassing System Object Model (SOM) class objects for a dynamic object-oriented language. A proxy class object is created using the dynamic language that points to the SOM class object. Next, a dynamic language subclass is created. This is followed by the creation of a SOM class object using the SOM interface, which causes certain SOM methods to be overridden by dynamic language redispatch stubs. The dynamic language overrides the SOM dispatch procedures and replaces the dispatcher with its own procedures. The new dispatch procedure will search for a method in the dynamic language class object method table first in response to a message, and if not found, redirects the message to the SOM environment.
