Abstract: A swim training apparatus for use as a monofin for bilateral undulation power development. The apparatus includes a flexible, elongated member having a series of securing members, such as through-holes extending from the top surface of the elongated member through to its bottom surface, and fasteners configured and disposed to attach to the securing member, such as straps that can extend through the through-holes, to fasten the apparatus to a user's legs. A weight can be attached using similar attachments and fasteners to the apparatus to increase undulation during use.

Abstract: Bedding material having a bed bug monitor. The bedding material includes at least one bed bug monitoring interface adapted to receive a bed bug monitor, whereby the monitor gathers bed bugs and/or evidence thereof and is subject to visual inspection.

Abstract: An aquatic training device including a body having a contact surface for engaging a hand of a user and a securing fin extending substantially transverse from the contact surface. The securing fin further includes a retaining member spaced from the contact surface. The aquatic training device is designed to improve a user's stroke technique, particularly with respect to hand arm positioning while swimming, by forcing the user to engage shoulders, arms, elbows, wrists, hands, and fingers in optimal hand arm positions while swimming.

Abstract: An underwater breathing apparatus including an elongated tube assembly and a fastener. The elongated tube assembly includes a central support having a first end and a second end opposite the first end, and a securing member. The elongated tube assembly further includes a first tube extending substantially transverse from the first end of the central support and a second tube extending substantially transverse from the second end of the central support. The central support is in fluid communication with the first and second tubes defining a continuous air passageway. The fastener is configured to engage the securing member and secure the elongated tube assembly to a user.

Abstract: A technique is provided for detecting episodes of cardiac ischemia based on an examination of the total energy of T-waves. Since cardiac ischemia is often a precursor to acute myocardial infarction (AMI) or ventricular fibrillation (VF), the technique thereby provides a method for predicting the possible onset of AMI or VF. Briefly, the technique integrates internal electrical cardiac signals occurring during T-waves and then compares the result against a running average. If the result exceeds the average by some predetermined amount, ischemia is thereby detected and a warning signal is provided to the patient. The maximum slope of the T-wave is also exploited. Techniques are also set forth herein for reliably detecting T-waves, which help prevent P-waves from being misinterpreted as T-waves on unipolar sensing channels. The T-wave detection technique may be used in conjunction with ischemia detection or for other purposes.

Abstract: A soldering tip for soldering irons having a mounting portion adapted to fit in a heater unit of a soldering iron or tip-heater cartridge and a soldering portion shaped for forming of a solder joint. At least the soldering portion is formed of a copper inner base material which is covered by a wear and corrosion resistant coating having a matrix of a metal that is harder than the copper inner base material in which micron size particles of a chemically inert material that is harder than iron are dispersed. The chemically inert material is preferably diamond, but can be ruby, sapphire, silicon, or alumina. The matrix material is preferably iron but can be formed of nickel, nickel alloys, nickel/phosphorous alloys. silver, silver alloys, gold, or gold alloys. Preferably, the coating forms a textured outer surface on the soldering tip.

Abstract: Exemplary methods and devices for analyzing intracardiac electrocardiograms (IEGMs) using statistical analysis (e.g., histograms, etc.), ensemble averaging and/or an ensemble average. Various methods and/or devices are suitable for use with atrial and/or ventricular pacing therapies. Other methods, devices and/or systems are also disclosed.
