摘要:
A method and apparatus for controlling the charge and discharge currents in a battery (2) as a function of temperature. When a battery (2) is charged or discharged in an environment that approaches its design operating temperature extreme, the currents are reduced to limit self-heating of the battery and thus extend the useful operating environment temperature range. A temperature sensor (18) is coupled to a controller (6) to sense the battery (2) temperature. The temperature information is used to set a suitable charging or discharging current (8). In the illustrative embodiment, the charging current is set to a maximum value when said temperature is lower than a first predetermined threshold value, the maximum value being the battery's maximum specified charging current, and the first predetermined threshold value being the battery's maximum charging temperature.

Apparatus for securing a first electrical connector mounted to an electronic module to a second electrical connector supported by a support structure, such that the first and second electrical connectors mate in an electrically conductive manner. The support structure can be an electrical board supported by a chassis. The apparatus includes a latch having a first end configured to engage the chassis and a lever portion configured to exert a force on the chassis when in a first position. This force allows the first electrical connector to be urged towards the second electrical connector. The apparatus also has a compliant member configured to bias the lever portion away from the first position, and a catch configured to secure the latch in the first position.

Methods and apparatus for securing a first electrical connector mounted to an electronic module to a second electrical connector supported by a support structure, such that the first and second electrical connectors mate in an electrically conductive manner. The support structure can be an electrical board supported by a chassis. The apparatus includes a latch having a first end configured to engage the chassis and a lever portion configured to exert a force on the electronic module when in a first position. This force allows the first electrical connector to be urged towards the second electrical connector. The apparatus also has a compliant member configured to bias the lever portion away from the first position, and a catch configured to secure the latch in the first position. In the method, a first force is applied to the electronic module to urge the electronic module towards the board from a first position to a second position to thereby cause the first electrical connector to mate in an electrically conductive manner with the second electrical connector. Thereafter a second force is applied to the electronic module to maintain the electronic module in the second position. The second force is selected to be not greater than a predetermined force.

Selecting a digital image. A method embodiment includes obtaining a first digital image of the first side of a physical object and obtaining a second digital image of a second side of the physical object. The first digital image is examined to determine if it is substantially blank. If the first digital image is determined to be blank, the second digital image is sent for processing. Otherwise, the first digital image is sent for processing.

A switch integral to an insert/extract latch assembly. The switch is positioned between a latch and a retainer and may be compressed between the latch and the retainer. The switch is connected to a warning circuit and may function to de-energize the electronic assembly upon disengagement of the latch from the retainer. The retainer is movable between first and second positions. In the first position, the retainer is disengaged from the latch, the switch contacts are open and the latch is free to operate. In the second position, the retainer is engaged with the latch, the switch is compressed between the latch and the retainer and the switch contacts are closed.

The invention includes a latch assembly movably mounted on a module. The module is removably supportably on a chassis, and movement of the latch assembly with respect to the module aids in removal and installation thereof. The invention also includes a sensor mounted on the module and configured to detect the movement of the latch assembly through a first range. The latch assembly must be moved through a second range in order to move the module relative to the chassis. However, the latch assembly is moved through the first range prior to moving through the second range. Thus, the sensor can detect imminent movement of the module relative to the chassis by detecting movement of the latch assembly through the first range. The latch assembly can be configured to be secured in a given position so as to prevent inadvertent movement of the latch assembly. The invention also includes a method for removal of a module which is supported on a chassis. The method includes moving a portion of the latch assembly through a first range and detecting that movement. The method also includes moving another portion of the latch assembly through a second range which results in movement of the module. The method can also include generating a signal in response to the detection of the movement of the latch through the first range.

A method and apparatus for determining the extent of skew present in a document being scanned using only the primary vision transducer. The primary vision transducer is wider than the width of the media to be scanned and logically divided into a central image gathering portion and marginal skew detection and image gathering portions.

A print apparatus includes a photoconductor and a mechanical system for moving the photoconductor past a scan line exposure station. The print apparatus includes a test signal generator for providing outputs indicative of the movement of the photoconductor. A first comparator produces a first position error signal that is derived from a difference between a reference signal and a position error signal output, such position error signal indicating that the position of the photoconductor differs from a predetermined print position that is determinable with respect to the reference signal. The print apparatus further includes a laser beam scanner and a beam detector for producing a scan position signal. A second comparator is responsive to the scan position signal and the position error signal from the first comparator to produce a beam deflection control signal that is applied to a beam deflector. The beam deflector moves the laser beam in a direction which reduces the beam deflection control signal and position the laser scan at a position closer to a predetermined print position.

Methods, systems, apparatuses, and arrangements enable an identifier module of a storage system to be rendered unusable upon removal from the storage system. In an exemplary identifier module implementation, the identifier module includes an identifier data space that is capable of receiving an identifier and a breakable apparatus that is adapted to break and render the identifier module unusable upon removal of the identifier module from a storage system. The identifier module may be adapted for removable attachment to the storage system. In an exemplary storage system implementation, the storage system includes one or more memory units that are capable of storing information and at least one interface that is adapted to receive an identifier module. The at least one interface includes a disrupter apparatus that is adapted to break and render unusable an identifier module upon removal of such an identifier module from the at least one interface.
