Abstract: In some examples, an apparatus includes a first metal layer having a thickness, a piezoelectric material layer having a first side and a second side that is opposite the first side, the piezoelectric material layer first side abutting the first metal layer, the piezoelectric material layer second side having recesses, and a second metal layer abutting the piezoelectric material layer second side, the second metal layer having extensions that fill the recesses to form a metal frame that is at least partially recessed into the piezoelectric material layer. The first metal layer, the piezoelectric material layer, and the second metal layer form a resonator body. The metal frame has a shape governing a resonant mode of the resonator body.

Abstract: A piezoelectric resonator includes a first conductive layer, and a piezoelectric layer affixed to a first side of the first conductive layer. The piezoelectric resonator also includes a stair step frame structure affixed to a first side of the piezoelectric layer, and a second conductive layer, affixed to the first side of the piezoelectric layer and covering the stair step frame structure.

Abstract: Funnel storage systems are presented including: a cabinet enclosure having an upper opening; a lid removably coupled with the cabinet enclosure, the lid forming a dust seal with the cabinet enclosure; a top screened support coupled with the cabinet enclosure for receiving a number of funnels; and a bottom screened support coupled with the cabinet enclosure for storing and organizing the number of funnels along a number of upright storage posts. In some embodiments, the cabinet enclosure further includes angled side walls such that a second cabinet enclosure having angled side walls may be nested within the cabinet enclosure.

Abstract: Sales information corresponding to one or more retailers is collected and stored. A customer/user can access the sales information using a client application running on his mobile device. The access may be responsive to a customer profile that establishes the customer's preferences or tastes. The access may be responsive to detecting that the customer's mobile device is within a threshold distance of one or more matching retailers. The access may be responsive to a customer request to obtain the sales information. One or more reminder notes may be sent to the customer to serve as a reminder that the customer likely needs to acquire a product or service.

Abstract: A flexible pour spout for transferring fluid from a container includes a resiliently deformable conduit having a closure cap removably attached at one end to prevent leakage of residual fluid during non-use and a threaded fitting frictionally engaged at the other end to permit fluid communication with the container. The fitting is comprised of a fastener and a spool having complementary bearing surfaces which permit a snap fit and may include a washer for sealing the interface between the container and the conduit.

Abstract: An oil dipstick guide which is a funnel-shaped guide mounted about the dipstick tube of a typical combustion engine. The guide has a circular lip on which an oil dipstick can be balanced when inserting the tip of the dipstick into the oil dipstick tube.

Abstract: An aquatic exercise apparatus for providing underwater cycling motions comprising a longitudinal support member with a pair of pedals connected to a single shaft which is journaled to an underwater bearing. A pair of cross-members support the apparatus on the bottom surface of a water receptacle and a plurality of suction cups are provided for attachment with the bottom surface.
