Abstract: An end-cap assembly for a ball bat or other sporting-good implement includes one or more removable weights, so that the weight of the end cap—and of the ball bat—may be adjusted. The one or more weights may reside in a receiving space or recess in an end-cap cup of the end-cap assembly. A fastener removably attaches the one or more weights to the end-cap cup. In some embodiments, the fastener may include threads that engage threads in a bore in the end-cap cup.

Abstract: A dissolvable medication administration bag for the safe and effective crushing and administration of medication to patients who have difficulty swallowing pills. A dissolvable medication administration bag may be constructed in accordance with a pill crusher pouch embodiment into which a pill is placed prior to being crushed and subsequently the whole of pouch and the crushed pill contents are dissolved into a liquid, e.g. a beverage, as a means of reducing health hazards associated with current pill crushing practices such as inadvertent direct contact and aerosolization with subsequent inhalation of the crushed medication.

In other embodiments, the dissolvable medication administration bag is constructed in accordance with a pre-packaged medicine dosage administration bag embodiment wherein the whole of the pre-packaged bag and its powdered or liquid form medication contents are dissolved into a liquid with no need for crushing.

Abstract: A ball glove includes a rear strap or back strap that is adjustable to accommodate different hand configurations and sizes. The back strap includes multiple spaced apart openings, or sets of openings, through which one or more laces or other connecting elements may be threaded. A user may adjust the length of the back strap by threading the laces through the openings that yield the best strap-length for his or her hand or wrist. The back strap optionally includes a top portion and a bottom portion that are detachably connected to each other, such that the top portion may be replaced with a different top portion embroidered with—or otherwise displaying—a wearer's jersey number, team logo, or other desired feature.

Abstract: A method of assessing a signal to identify particular signal characteristics comprises application of machine learning to multi-dimensional histograms derived from multi-tap sampling of the signal. The signal is sampled from at least two tap points to retrieve a sample set, and the at least two tap points are adapted to retrieve distinct samples from the signal, such as time spaced samples or spectrally distinct samples. Multiple sample sets are retrieved from the signal over time. The at least two dimensional histogram is built from the joint probability distribution of the plurality of sample sets. A machine learning algorithm then processes the multi-dimensional histogram, and is trained to predict a value of at least one characteristic of the signal.

Abstract: A batting glove includes a strap or cuff that folds about a seam or hinge line to shorten the length of the glove. Hook and loop material, or another suitable fastener, is included on the inside of one end of the strap or cuff, and on the outside of a free end of the strap or cuff, when the glove is in its full length position. Accordingly, when the strap or cuff is folded back about the hinge line to shorten the length of the glove, the fastener previously on the inside of the strap is exposed, allowing the wearer to secure the fastener on the free end of the strap or cuff to the exposed fastener.

Abstract: Monitoring an optical signal comprises sampling the optical signal from two or more distinct tap points to retrieve a sample set. Multiple such sample sets are obtained over time. A joint probability distribution or phase portrait of the sample sets is assessed for indications of optical signal quality. The tap distinction can be polarization, for example to determine OSNR, or frequency. The tap distinction can be a time delay, which can enable diagnostic differentiation between multiple impairments, such as OSNR, dispersion, PMD, jitter, Q, and the like. Machine learning algorithms are particularly suitable for such diagnosis, particularly when provided a two dimensional histogram of sample density in the phase portrait.

Abstract: A method and device for determining in-band noise of an optical signal. The optical signal is split to produce two optical signal components, of distinct polarisation, such that the respective noise component in each signal component is uncorrelated. The optical signal components are converted to the electrical domain to produce electrical signal components. The signal component powers are equalised either in the optical domain or the electrical domain. The equalised electrical signal components are then subtracted together to cancel the correlated portions of the signal components (e.g. the data signal), such that only uncorrelated signal components (e.g. noise) are output for measurement.

Abstract: A glove apparatus having a front shell for fielding a ball and a back shell joined to the front shell. The front and back shells cooperate to define a finger region, a heel region, and a thumb region. The ball glove provides more comfort and control than previous gloves. The ball glove may also be lighter weight than conventional gloves of comparable size. A traction panel may be formed in the back shell adjacent an index finger hole.

Abstract: A glove that includes a glove closure apparatus in the form of a closure channel that allows the glove to be more easily closed or compressed without requiring extensive breaking-in procedures. In one embodiment the glove includes one or more closure channels near the palm portion of the front side of the glove. The closure channels are U-shaped closure channels or gaps that allow the glove to be compressed significantly easier than if the material were otherwise in the channel area. A plurality of closure channels may be formed at specific locations on the front side of the glove to reduce the amount of force that is required to close and open the glove. In addition, the one or more closure channels may include a cover material to prevent debris from entering into an interior region of the glove.
