Abstract: Aspects of the disclosure relate to determining vehicle operation modes for a fleet of vehicles. This may include maintaining a storage system including vehicle parameters for a vehicle fleet such that each vehicle of the fleet is associated with a set of vehicle parameters. The vehicle operation mode may be determined by selecting one of a plurality of vehicle operation levels arranged in a hierarchy or by identifying a set of tags where each level or tag corresponds to a vehicle driving capability. The determined vehicle operation mode may be communicated to the given vehicle in order to cause the vehicle to operate according to the determined vehicle operation mode.

Abstract: Disclosed is a design methodology which facilitates increasing the system mode frequency of an actuator system. As a first step, the primary components of a given actuator system are analyzed to determine which component is most responsible for limiting the system mode frequency of the given system. That component is then stiffened, resulting in a new actuator system with a higher system mode frequency. A second analysis step may then be performed to determine whether the modified design is optimal. These steps may be repeated as parts of an iterative process resulting in an optimal actuator design.

Abstract: A jacket for holding and retaining a disk drive unit in a computer device bay. The jacket protects the disk drive unit from damage during handling, use and storage. The configuration of the jacket permits electrical and electrical ground coupling of the disk drive unit to a computer device bay. The configuration of the jacket also permits engagement with a retaining mechanism in the computer device bay, and permits ejection from the computer device bay without imparting an excessive shock load to the disk drive unit.

Abstract: A pager device received paging messages. The user reads a paging message, selects one of a set of stored, predetermine reply messages, and transmits the selected reply message from the pager. The reply signal is received by one of a set of local cellular receivers, which sends the received signal to a computer for interpretation. The computer initiates an action based on interpretation of the received reply signal. The communication system communicates with large numbers of pagers in a time and energy efficient manner. The pagers are associated with items located in a communication region that is interrogated by an interrogator on a one-to-many basis using broadcast commands, on a one-to-one basis using directed commands or on a combination basis using both methods. Messaging occurs through organized transmission and reception of signals between the pagers and the interrogator.

Abstract: A communication system for identifying, locating, tracking and communicating for other purposes with large numbers of tags in a time and energy efficient manner. The tags are associated with items located in a communication region that is interrogated by an interrogator on a one-to-many basis using broadcast commands, on a one-to-one basis using directed commands or on a combination basis using both methods. Identification occurs through organized transmission and reception of signals between the tags and the interrogator. A batch collection protocol uses a combined one-to-many and one-to-one communication system that effectively resolves communication contentions. The batch collection protocol employs a plurality of collection periods which communicate with large or unknown numbers of portable tags.
