An image processing apparatus for compositing multiple component images into a composite image is proposed. The timing for the alert may be set by the user at the beginning of each call, or may be automatically configured during the initiation of a call or communication. The invention further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic lettuce plants and plant parts produced by those methods. The piezoelectric actuator is fixed onto the cavity unit to seal the pressure chambers. The test harness can intercept all of the device access calls. User information in each of the defined categories, that is, environment, circumstance, condition, request, action, and situation, is then described using item values, and operating units infer the item values.
