Elliot Handler doll, Chatty Cathy, using a pull string talking mechanism, revolutionizing the toy industry. Mattel continued to develop a number of talking toys, including Chatty Baby, Tiny Chatty Baby, and Charmin' Chatty. Toys were made for cartoon favorites such as Bugs Bunny and Porky Pig, and for television characters such as Herman Munster and Mr. Ed. Handler was primarily responsible for two additional Mattel product lines. In 1966, Mattel introduced smaller dolls called Liddle Kiddles. Handler claimed he wanted them to resemble little children in neighborhoods across America. They were sculpted by doll artist Martha Armstrong-Hand. Kiddles were a great success
Interrupt handler interrupts are often provided, which exacerbates stack usage. A primary constraint on the interrupt handler in this programming endeavour is to not exceed the available stack in the worst-case condition, requiring the programmer to reason globally about the stack space requirement of every implemented interrupt handler and application task. When allocated stack space is exceeded (a condition known as a stack overflow), this is not normally detected in hardware by chips of this class. If the stack is exceeded into another writable memory area, the handler will typically work as expected, but the application will fail later (sometimes much later)
