Title: Method and apparatus for molding fruits
Inventor: TWEDDELL III RICHARD
IPC: A01G7/00
Filed: 1987-03-16
Abstract: In a method for growing squash, cucumbers and other fruits in desired shapes. The fruit, while growing on the plant, is enclosed within the internal cavity of an oversized mould having a cavity (inside) surface configured to form the desired details on the fruit. As growth continues the fruit fills the cavity and in doing so conforms with remarkable fidelity to the internal details of the mould. The mould is opened or removed when the fruit has filled the cavity, and the fruit is removed from the plant. The fruit can be eaten or, if dried, can provide a long-lasting sculptural item. Moulds for growing fruit in desired shape are described and claimed. <IMAGE>

Title: Content-based depictions of computer icons
Inventor: BAECKER RONALD M
IPC: G06T13/00
Filed: 1991-01-17
Abstract: A means and method for generating and displaying a content-based depiction of a standard icon on the display of a computer is disclosed. The depiction is generated upon the occurrence of predetermined events, such as the closure of the document or file associated with the icon, and is displayed in either a static or animated form in place of the standard icon in response to selection signals from a selection device. A single content-based depiction of an icon is generated by creating a representation of the object (file or document) to be depicted, and translating this representation into a scaled-down replica of the representation. This representation may be in the form of a bit-map, a full-scale image, etc. The replica is created by partitioning the representation into a number of equal segments, measuring the percentages of different colors (black and white, gray scale, or color) within each segment, and assigning a single color value to each display element or pixel of the replica based upon the color percentage measured from each corresponding segment of the representation. Animated depictions are created by forming a number of different replicas for each representation to be depicted and then displaying those replicas in a serial sequence to create an animated depiction of the representation. Like the icons these depictions replace when selected, the depictions would be movable to any position on the display through use of the mouse. <IMAGE>

Title: Measuring distortion
Inventor: ANDREWS CHRISTOPHER JOHN
IPC: G01R23/20
Filed: 1991-05-08
Abstract: In a method of analysing the distortion produced by a linear power amplifier two tones are applied to the amplifier 20 and the resulting down-mixed signal at 26 is periodically sampled at 28 and subjected to a FFT in order to derive the spectrum and plot the amplitude and phase distortion against the two tone amplitude. Analysis of the results of such testing throughout the frequency range of the amplifier allows pre-distortion circuits to be designed to compensate for distortion produced by the amplifier over the complete operating frequency range of a transmitter. The pre-distortion circuits may include combinations of diodes with resistors, capacitors or inductances. <IMAGE>
