4-H Indoor Gardening Project: Making a Desert Dish Garden Prepared by Madge Balden Adams, former special assignment writer for Horticulture Evaporation is slowed down by protective coverings of wax or hairs or by a reduced surface area. (Many succulent plants have a spherical shape because a sphere has the smallest surface area for a given volume.) Succulents grow naturally in semi-deserts where long, dry periods are broken by short, rainy periods. Cacti are one kind of succulent. What to Do Materials Plants With just a few essentials, a few minutes, and your creativity, you can make a desert dish garden. All you need are some cacti or other slow-growing succulent plants, a shallow dish, and sand. That’s it. And the best part is that your garden in a dish will last for years with very little care. Succulents raised in dish gardens are even easier to care for than are single specimens. Fertilization is not needed because you do not want the plants to outgrow the container. You can buy cacti and other succulent plants from a ﬂorist or at a garden store that has a plant section. Choose plants of different sizes and shapes that will go well together to make an interesting garden. Choose plants that are in scale with the container you plan to use. Select small plants that grow slowly. Plants should ﬁll the container but not crowd it. Some suitable plants are:...
Overview of the U.S. Patent Classification System (USPC) 1.1 The USPC The USPC is a system for organizing all U.S. patent documents and many other technical documents into relatively small collections based on common subject matter. Each subject matter division in the USPC includes a major component called a class and a minor component called a subclass. A class generally delineates one technology from another. Subclasses delineate processes, structural features, and functional features of the subject matter encompassed within the scope of a class. Every class has a unique alphanumeric identifier, as do most subclasses. A class/subclass pair of identifiers uniquely identifies a subclass within a class (for example, the identifier “2/456” represents Class 2, Apparel, subclass 456, Body cover). This unique identifier is called a classification symbol, or simply a classification, or USPC classification, to distinguish it from classifications of other patent classification schemes. A subclass represents the smallest division of subject matter in the USPC under which documents may be collected. A collection of documents is defined as a set of documents sharing a common classification. A classification assigned to a document associates the document to the class and subclass identified by the classification. Documents are “classified in a subclass” if a classification corresponding to the unique subclass has been assigned to it. A document may be a member of more than one collection, i.e., it may have more than one classification assigned to it. Classifications are assigned to documents based on disclosure in the document. The USPC includes the following: • The Manual of Classification (MOC). The MOC is an ordered listing of all the valid classifications in the USPC. Classifications are presented in the MOC as class schedules. A class schedule is a listing of all the subclasses in a class in top-tobottom order of classification precedence, with the most complex and comprehensive subject matter generally at the top of the schedule, and the least complex and comprehensive at the bottom. Class schedules are arranged in the MOC in numerical order; for example, the schedule for Class 2 appears before the schedule for Class 224. The MOC is published electronically in HTML and PDF versions, which are available from the internal and external USPTO Web sites, respectively.

Optimization Problems EXAMPLE 1: A farmer has 2400 ft of fencing and wants to fence oﬀ a rectangular ﬁeld that borders a straight river. He needs no fence along the river. What are the dimensions of the ﬁeld that has the largest area? Solution: Note that the area of the ﬁeld depends on its dimensions: To solve the problem, we ﬁrst draw a picture that illustrates the general case: The next step is to create a corresponding mathematical model: Maximize: A = xy Constraint: 2x + y = 2400 We now solve the second equation for y and substitute the result into the ﬁrst equation to express A as a function of one variable: 2x + y = 2400 =⇒ y = 2400 − 2x =⇒ A = xy = x(2400 − 2x) = 2400x − 2x2 To ﬁnd the absolute maximum value of A = 2400x − 2x2 , we use THE CLOSED INTERVAL METHOD: To ﬁnd the absolute maximum and minimum values of a continuous function f on a closed interval [a, b]: 1. Find the values of f at the critical numbers of f in (a, b). 2. Find the values of f at the endpoints of the interval. 3. The largest of the values from Step 1 and 2 is the absolute maximum value; the smallest value of these values is the absolute minimum value. We ﬁrst note that 0 ≤ x ≤ 1200. The derivative of A(x) is A′ (x) = (2400x − 2x2 )′ = 2400 − 4x, so to ﬁnd the critical numbers we solve the equation 2400 = 600 2400 − 4x = 0 =⇒ x = 4 To ﬁnd the maximum value of A(x) we evaluate it at the end points and critical number: A(0) = 0, A(600) = 2400 · 600 − 2 · 6002 = 720, 000, A(1200) = 0 The Closed Interval Method gives the maximum value as A(600) = 720, 000 ft2 and the dimensions are x = 600 ft, y = 2400 − 2 · 600 = 1200 ft. EXAMPLE 2: We need to enclose a ﬁeld with a rectangular fence. We have 500 ft of fencing

Each “camera unit” contains a lens, an image sensor and an image-processing engine. By changing units, the photographer can handle a diverse range of scenes. The camera’s slide-in mount system enables the user to change units quickly and securely. This design offers several advantages: Because the lens and sensor are contained in a single unit, you don’t have to worry about dust getting on the sensor, as you might with a camera that uses interchangeable lenses. Only two units are currently available, but Ricoh plans to release a variety in the future, including photo viewers and projectors. Richoh claims the GXR is “the world’s smallest and lightest digital camera with the ability to change lenses.”
