Abstract: Disclosed herein is a device for modeling properties of an ear. The device includes an artificial tympanic membrane and a housing coupled to the artificial tympanic membrane. The housing defines an interior portion coupled to an interior surface of the artificial tympanic membrane. The interior portion has an adjustable volume or an adjustable type of fluid and an adjustable gas pressure. Adjustment of the volume or type of fluid and the gas pressure changes a membrane movement to produce selected movement properties according to a mobility scale.

Abstract: Disclosed herein are systems and methods for classifying a tympanic membrane by using a classifier. The classifier is a machine learning algorithm. A method for classifying a tympanic membrane includes steps of: receiving, from an interrogation system, one or more datasets relating to the tympanic membrane; determining a set of parameters from the one or more datasets, wherein at least one parameter of the set of parameters is related to a dynamic property or a static position of the tympanic membrane; and outputting a classification of the tympanic membrane based on a classifier model derived from the set of parameters. The classification comprises one or more of a state, a condition, or a mobility metric of the tympanic membrane.

Abstract: An ultrasound signal processor uses an excitation generator to cause displacement of a membrane or surface while a series of ultrasound pulses are applied to the membrane or surface. Phase differences between a transmitted signal and received signal are examined to determine the movement of the membrane or surface in response to the applied excitation. An examination of the phase response of the membrane or surface provides a determination as to whether the fluid type behind the membrane or surface is one of: no fluid, serum fluid, or purulent fluid.

Abstract: A system and method for examining a patient for an ear disorder. Reflectance ultrasound is applied to a portion of the ear to determine the presence of ear effusion in a middle ear. If ear effusion is present, motion of the tympanic membrane is induced and ultrasound is further applied to the moving tympanic membrane. Echo signals resulting from the ultrasound applied to the moving tympanic membrane are analyzed to obtain information regarding the motion of the tympanic membrane and is used to characterize the ear effusion.

Abstract: A tool holder for use with an ATV comprises an attachment base, attachable to a portion of the ATV, and a holding member extending from the attachment base. The holding member is configured to receive and hold a tool therein and includes a pair of generally upright arms which collectively define a containment area therebetween. At least one of the pair of generally upright arms includes at least one stress relief section formed therein, the stress relief section including a cross section relatively more narrow than remaining cross sections of the at least one of the pair of generally upright arms.

Abstract: A mounting bracket for use in mounting at least one auxiliary device to an ATV includes a body and an engaging section, associated with the body. The engaging section is configured to engage a portion of the ATV to limit movement of the body relative to the ATV in at least one degree of freedom. Connecting means are associated with the body for connecting the body to the portion of the ATV. An auxiliary device receiving area is coupled to the body and is operable to receive and secure an auxiliary device to the bracket. The receiving area is formed of a material having a hardness relatively greater than a hardness of the body.

Abstract: A bag filling and sealing machine includes a bag holder, a bag opening and filling station, and a sealing station. The bag holder holds wicketed bags in a manner that allows the bags to be easily torn from the holder. A funnel assembly successively opens each bag, tears the bag from the bag holder, fills the bag with material, and releases the bag to a grabber assembly. The grabber assembly engages the sides of the bag while the bag is attached to a funnel assembly and later pulls the sides of the bag away from each other so that the top of the bag is closed and ready to seal when the bag is delivered to a sealing apparatus. The grabber assembly moves in a manner so as to minimize the lost height when moving from the filling station to the sealing station.

Abstract: An extender for a thumb throttle of a vehicle includes an attachment section attachable to the throttle of the vehicle. An extension section extends from the attachment section and is configured to extend beyond an end of the thumb throttle. The attachment section has at least two channels formed in an outer face thereof, the two channels extending across the attachment section from a first side of the outer face to a second side of the outer face. The two channels are configured to each receive at least a portion of a securing device therein to securely attach the extender to the throttle.

Abstract: A utility holding device attachable to a vertical surface for carrying elongated objects such as rifles, bows, fishing rods and the like. The device can be attached to a vertical surface such as a wall or a window, and is specifically intended to be used on the interior surface of a vehicle such as a truck or boat. The device includes a base unit which is permanently attached either by adhesive or screws to the vertical surface. The base unit includes the female portion of an attachment member. The device further includes a mounting stem which includes the male portion of the attachment member and which also includes either a large holding unit integrally formed therewith or adjustably attachable thereto. The female and male portions of the attachment member being interlockable to rigidly attach the stem and base unit. The holding unit may also include a hold-down member which can encircle an item such as a rifle to prevent its removal therefrom.
