Abstract: A hand held ultrasound system is disclosed. By use of a curved reflector for focusing sound energy reflected by a structure being imaged a simple, lightweight, and power efficient device is presented. A transmitter directs a sound wave into a patients body, a structure to be imaged reflects some of the sound wave, a curved reflector focuses that sound energy onto one or more receivers. If more than one receiver is used they do not need to be phased since this function is performed by the curved reflector. The reflector may be spherically shaped or ellipsoidal. The device can function in either mono-static mode or bi-static mode depending on the depth of focus required, e.g., for imaging structures close to the skin surface (blood vessels and the like) an ellipsoidal shaped reflector is used since it provides a very short or close-up depth of focus. The device provides good resolution while using relatively little power making the device light in weight and small in size.

Abstract: A nursing shawl having a crinoline portion, a tail portion and a securing means. Said crinoline is self-supporting due to a plurality of pleats formed therein. The pleats allow the crinoline to fold down into a compact stack of material which is easily stored in a purse or pocket. One end of the crinoline is sewn together preventing the pleats from separating while the other end is openable, thereby allowing it to be opened up like a paper fan. The sewn end is also sewn to a weighted tail that holds the shawl in place over a women's shoulder while in use. The shawl provides a tent-like structure under which a baby can be discretely nursed in a public location.
