Abstract: A multi-function mobility device may comprise a lower chassis shell and an upper occupant shell connected by a quick release pivot joint that provides occupant accommodation that is secure and comfortable. In addition, the structural architecture is designed to allow safe adaptations to the axle configuration. Through flexible suspension arm mounting the suspension-hub-wheel/tire assembly can be quickly assembled/disassembled to provide alternative usage axle layouts. An ergonomic handle assembly may be coupled with the structure for pushing, pulling, towing, carrying, etc. When disassembled, the multi-function stroller can be folded into a compact storage mode. Thus, non-compromised performance, versatility, and usage functionality can be readily achieved and accomplished in a safe manner.

Abstract: A modular transporter comprises a universal chassis that can be linked with a variety of user modules. The universal chassis comprises a base that includes a quick connector and complex geometric surfaces on its sidewalls that function to secure a user module thereto. The quick connector allows for quick assembly/disassembly of a user module to and from the base of universal chassis. A plurality of suspension arms may be removeably connectable to the base such that modular transporter may be configured in a number of transport configurations. An ergonomic handle assembly may be coupled with the base for pushing, pulling, towing, etc. When disassembled, the modular transporter can be folded into a storage and/or quick fold mode and stored in a modular storage system. The modular storage system can be mounted to a trailer hitch by a linking mechanism for further transport.

Abstract: Systems and methods relate to division of a dividend by a divisor, with fast result formatting. Counts of leading sign bits of the dividend and the divisor are determined. The dividend and the divisor are normalized based on their respective counts of leading sign bits to obtain a normalized dividend and a normalized divisor, respectively. An exact number of significant quotient bits of a quotient of the division, based on the normalized dividend, the normalized divisor, and the counts of leading sign bits of the dividend and the divisor and used to determine a correct position of a leading bit of the quotient based on this exact number. The quotient is developed by placing the leading bit at or near the correct position and appending less significant bits to the right of the leading bit. Thus, left-shifts in each iteration and large final shifts are avoided in formatting the result.

Abstract: Systems and methods relate to a division/root computation unit. A lookup table according to a Sweeney, Robertson, and Tocher (SRT) algorithm for a division/root computation is stored in a memory. Information related to a selected column corresponding to a divisor/root estimate is stored in a high-speed memory. Division/root computation is performed iteratively using the cached information to improve access times and reduce latency of accessing the entire lookup table on each iteration. In each iteration, a quotient/root is determined from the cached information based on a current partial remainder, and a next partial remainder is generated based on the quotient/root, the divisor/root estimate, and the current partial remainder.

Abstract: In a denormal support mode, the normalization circuit of a floating-point adder is used to normalize or denormalized the output of a floating-point multiplier. Each floating-point multiply instruction is speculatively converted to a multiply-add instruction, with the addend forced to zero. This preserves the value of the product, while normalizing or denormalizing the product using the floating-point adder's normalization circuit. When the operands to the multiply operation are available, they are inspected. If the operands will not generate an unnormal intermediate product or a denormal final product, the add operation is suppressed, such as by operand-forwarding. Additionally, each non-fused floating-point multiply-add instruction is replaced with a multiply-add instruction having a zero addend, and a floating-point add instruction having the addend of the original multiply-add instruction is inserted into the instruction stream.

Abstract: The subject invention provides an independent wheel suspension system (20) for a vehicle. The suspension system (20) includes an lateral support (26) and a pair of lower lateral links (30, 32) spaced from the lateral support (26). A tall knuckle (36) extends between the lateral support (26) and the pair of lower lateral links (30, 32). The lateral support (26) and the pair of lateral links (30, 32) are pivotably connected to the knuckle (36). A rod (64) is pivotably connected to the knuckle (36) adjacent the pivotal connection between the lateral support (26) and the knuckle (36) and extends inward and downward toward the vehicle to a second end (68). A crank (70) is pivotable connected to the vehicle for rotation by the rod (64) in response to vertical movement of the knuckle (36) relative to the vehicle. The second end (68) of the rod (64) is connected the crank (70). A dampening device (72) is attached to the vehicle and the crank (70) for controlling movement of the crank (70).
