An adjustable spinal fixation system is composed of a collection of anchoring assemblies attached, via a variety of connectors, to spine-stabilizing rods. The anchoring assemblies include a linking member attached in a ball-and-socket fashion to a bone-engaging member that is adapted to engage a spinal bone of a patient. The linking member joins one of the included connectors to an associated bone-engaging member. The connectors are selectively attached to one of the stabilizing rods. The anchoring assemblies each include a support collar and a split retention ring that cooperate to allow adjustment of the bone-engaging member and corresponding connector during surgery. When surgery is complete, a linear engaging fastener cooperates with the support collar and split retention ring to maintain the relative position of the entire fixation system, preventing unwanted movement between the system components.

A shower arm attachment assembly may include a shower pipe coupling member, an arm coupling member, and a locking nut or sleeve. The shower pipe coupling member connects to a shower pipe, and the arm coupling member fluidly connects to a showerhead arm. The arm coupling member may be joined to the shower pipe coupling member. The arm coupling member may be selectively rotatable relative to the shower pipe member. Rotation of the arm coupling member relative to the shower pipe coupling member may be selectively controlled by selectively engaging a locking nut with the coupling members or selectively engaging a keying feature associated with one or both of the coupling members. Rotation of the coupling members relative to each other causes rotation of a showerhead relative to a shower pipe attached to the showerhead using the attachment assembly.

Snap fittings between the cartridge and handle assembly are provided at the fulcrum and also at a spaced location where an operating pin of the cartridge engages intersecting slots in the flanges. Overdrive protection of three different types is contemplated along with a structure facilitating operation of the handle assembly by palming a pair of handle bars.

A system for preventing accurate disassembly of computer code. Such code masking, referred to as “obfuscation,” is useful to prevent unwanted parties from making copies of an original author's software, obtaining valuable information from the software for purposes of breaking into a program, stealing secrets, making derivative works, etc. The present invention uses assembly-language instructions so as to confuse the disassembler to produce results that are not an accurate representation of the original assembly code. In one embodiment, a method is provided where an interrupt, or software exception instruction, is used to mask several subsequent instructions. The instruction used can be any instruction that causes the disassembler to assume that one or more subsequent words, or bytes, are associated with the instruction. The method, instead, jumps directly to the bytes assumed associated with the instruction and executes those bytes for a different purpose. A preferred embodiment works with a popular Microsoft “ASM” assembler language and “DASM” disassembler. The instructions used to achieve the obfuscation include “INT” instructions. Using this approach up to 17 bytes of obfuscation can be achieved with five instructions. Each instruction remains obfuscated until executed and returns to an obfuscated state afterwards.
