This invention packages option devices, such as floppy drives and hard disk drives, within an enclosure, thereby providing EMI/RFI shielding, promoting unimpeded option device electronic signaling, and reducing wasted space within an enclosure, such that small enclosures may encase the components. This invention includes a cage, for holding option devices, that is groundingly mounted in spaced relation to the major surface of a logic board, and an option device bracket that is slideably mounted within the cage. Each of the option device brackets contains one option device.

This invention is a system for self guiding interengagement of a securement member within a mating member having a slot for holding and securing two surface areas. The securement member is attached to one surface area and the mating member is attached to the other surface area. The securement member has a shape and the mating member has a tongue with a guiding surface, thereby promoting self guiding interengagement of the securement member within the slot of the mating member. The system is convenient for inserting a board within the obstructed view of a receptacle, such as a computer enclosure.

A method of testing a battery is provided the method may include: (a) applying a heavy load to the battery, (b) measuring the voltage V1 between the positive and negative terminals of the battery after a first time period under which the battery is subjected to the heavy load; (c) removing the heavy load, (d) waiting for a second length of time, (e) reading the voltage across the positive and negative terminals after the second length of time V2, (f) performing a cold cranking amps CCA test if the CCA test indicates a CCA value above a first threshold, then consider V2, if V2 is below the second threshold than skip to step g but if V2 is above a second threshold than determine if the V2 is above a third threshold, if V2 is above a third threshold than determine that the battery is good and skip steps g-h; but if V2 is below the third threshold then if a battery charge flag has been set, determine that the battery is bad and skip steps g and h, if the battery charge flag has not been set, determine that the battery is good but needs additional charging and skip steps g-h, if the CCA test indicates a CCA valve below the first threshold then move to step g, (g) determine if the battery charge flag has been set, if the battery charge flag has been set, then determine that the battery is bad, if the battery charge flag has not been set then move to step h; and (h) applying a charging current to the battery if the charging current is less than a fourth threshold amount then stop charging the battery and return to step a, if the charging current is greater than the fourth threshold amount, then charge the battery for a third length of time then stop charging the battery and return to step a.

In accordance with some embodiments of the present invention, a battery testing apparatus and method include a processor, a first clamp coupled to the processor, a second clamp coupled to the processor, and a third clamp coupled to the processor wherein the processor is configured to collect data on a current flow when the first and second clamps are connected with a first battery and the third clamp is connected to a conductor connecting the first battery with a second battery connected to the first battery in parallel. The processor is further configured to process the data to determine whether the first battery is stronger than, weaker than or the same capacity as the second battery.
摘要:
A method and apparatus for sensing the temperature of each individual cell of a battery during the testing and charging. The method and apparatus can monitor the temperature of the cells of the battery, the charger or both. Additionally, a user can be notified when the temperature is at or exceeds a predetermined level. The temperature data is also used to aid in efficiently charging the battery and determining of the battery is defective.

The present invention provides a system and method that enables a user to easily and efficiently determine a battery pack's rated current capacity without knowing the configuration of the batteries within the battery pack. Thus, the present invention enables a user to avoid manually calculating the battery pack's configuration. Furthermore, in some situations, the present invention enables a user to avoid having to disconnect and individually test the battery pack's batteries.

A sensor failure accommodation system includes a control computer receiving a sensor signal corresponding to an engine operating condition, and estimating a value of the engine operating condition as a function of one or more engine operating parameters different than the engine operating condition. The computer is operable to control one or more air handling mechanisms as a function of a final engine operating condition value, and if the sensor producing the engine operating condition signal is error free the final engine operating condition value is the engine operating condition signal. If the sensor producing the engine operating condition signal has failed, the final engine operating condition value is the engine operating condition estimate, and if at least one sensor producing the one or more engine operating parameters has also failed, the final engine operating condition value is a commanded or other definable engine operating condition value.
