Three weeks into the medical leave he took "to focus on my health," Apple CEO Steve Jobs was staying closely involved in the company's strategic decisions and product development, according to people familiar with the matter cited Friday by The Wall Street Journal.

The 55-year-old Jobs, whose ailment was not disclosed, was taking business meetings at home and on the phone, the sources said. He was also spotted on Apple's Cupertino, Calif., campus and in public in Palo Alto, Calif., with a company executive, according to people familiar with the matter.

Among products he was working on are the next version of the iPad, expected out in the next couple of months, and a new iPhone, expected to be released this summer, said two of these people.

Reports Tuesday said that Apple started manufacturing a new iPad, which includes a front-facing camera and other new features and will be available through Verizon Wireless and AT&T.

Inside Apple, meanwhile, day-to-day operations continued nearly unchanged under chief operating officer Tim Cook, said people inside the company and at its business partners. While several of them said there was a sense of sadness about Jobs' health struggles, they said Apple employees were focused on their jobs and projects.

"Steve is the CEO of Apple, and during his medical leave, he'll continue to be involved in major strategic decisions," said an Apple spokeswoman. Jobs and Cook did not respond to requests for comment.

Jobs, who was treated for a rare form of pancreatic cancer in 2004 and got a liver transplant in 2009, said in January that he would take a leave of absence for an unspecified period. Although his health status remains unclear, the company said it would say no more about his condition.

Wall Street so far appears to be unfazed by his medical leave. Apple's stock has risen about 1.7 percent to $354.54 since he announced the leave Jan. 17.
