Endoscopic bite block

An endoscopic bite block, with teeth position defining regions which guide the subject's teeth to grip the bite block in their natural position, with the teeth of the upper jaw positioned further out than the lower jaw teeth. These teeth position defining regions are also preferably curved to match the curved shape of the jaw. The upper and lower parts of the front plate of the bite block may also be positioned at different distances out, so that upper and lower lip regions both contact the front plate snuggly. The bite block may be used with separate oral / nasal cannulae, or may incorporate breath sampling or gas supply cannulae. A flexible flapped curtain at the outer end of the bite block may be provided to largely enclose the inner volume of the bite block to enable more accurate capnographic sampling under conditions of wide-open mouth breathing.

Filtering policies for evaluation by an embedded machine

Some embodiments provide a method for limiting data passed between an application and a process virtual machine (VM) embedded in the application that authorizes API (Application Programming Interface) calls to the application. The method receives a policy code comprising references to a group of parameters. The method modifies the policy code to remove references in the policy code to a set of the parameters that are not used during evaluation of the policy. The method generates a set of binary instructions from the modified policy code, where the process VM does not use the set of parameters while executing the binary instructions to make an authorization decision for a particular API call.

Channel tracking using step size based on norm-1 based errors across multiple OFDM symbols

A channel tracking module, configured for generating updated equalization coefficients for a frequency equalizer, is configured for determining a digital-based error value between equalized signals output by the frequency equalizer relative to predicted signals, for each subcarrier frequency of an OFDM symbol. The channel tracking module determines an accumulated error based on accumulating the digital-based error values for all the subcarrier frequencies of the OFDM symbol, for a prescribed successive number of OFDM symbols. The channel tracking module also determines a step size based on the accumulated error and relative to a prescribed step function configured for optimizing equalizer adjustments within stability limits. The channel tracking updates the equalization coefficients for each subscarrier frequency based on the accumulated error and the step size. Hence, the channel tracking module can be implemented in an economical manner while ensuring optimum equalizer adjustments within stability limits that ensure convergence of the equalization coefficients.
